- Abstract Micrometer-sized, monodispersed silicone hollow particles are functional materials with properties attributed to both their hollow structure and the silicone composition. However, there are few reports on their preparation. We have successfully prepared these particles by combining an original suspension polymerization technique, the self-assembling phase-separated polymer method, with a molecular diffusion method. The resulting particles exhibit heat resistance owing to the silicone matrix and maintain their hollow structure even after heating to 900 °C.Oxford University Press (OUP), Dec. 2024, Chemistry Letters, 54(1) (1)Scientific journal
- Abstract Single hollow particles are used in various fields, particularly in thermal insulation materials, owing to their low thermal conductivity attributed to encapsulated air properties. “The self‐assembling phase separated polymer (SaPSeP) method” is an original hollowing method that is proposed by this laboratory 25 years ago. Most hollow particles prepared by the SaPSeP method have carbon, oxygen, and hydrogen polymer shells, which lack sufficient heat resistance. In this study, hollow particles with a silicone shell, which is highly heat‐resistant, are prepared using the SaPSeP method using a trimer of 3‐methacryloxypropylmethyldimethoxysilane (MPDS). The MPDS trimer (3MPDS) is synthesized through the sol–gel reaction of MPDS with a basic aqueous solution. Additionally, hollow particles are prepared using a new silicone oligomer composed of MPDS and dimethoxymethylvinylsilane (DMVS). Both hollow particles prepared from 3MPDS and from a new silicone oligomer composed of MPDS and DMVS showed high heat resistance. They maintained their hollow structure even when exposed to temperatures up to 900 °C.Wiley, Dec. 2024, Macromolecular Reaction EngineeringScientific journal

- Abstract Hollow polyimide (PI) particles were successfully prepared using chemical imidization with acetic anhydride and pyridine as the chemical imidization reagents. The imidization reagents were added to the dispersion in which N,N-dimethylformamide (DMF) droplets with dissolved poly(amic acid) (PAmA, the precursor of PI) were dispersed in a cyclohexane medium. In the absence of poly(n-butyl methacrylate) (P[n-BMA]) in PAmA/DMF droplets, approximately 10% of the PI particles had hollow structures. Conversely, in the presence of a small amount of P(n-BMA) in PAmA/DMF droplets (0.2∼1 wt%), all PI particles had hollow structures. The P(n-BMA) would affect the phase separation of the PI in the droplets, thereby promoting the formation of a hollow structure.Oxford University Press (OUP), Dec. 2023, Chemistry Letters, 53(2) (2)Scientific journal

Abstract Effect of divalent metals was studied in the cross-coupling polymerization of thiophenes leading to head-to-tail-type poly-3-hexylthiophene. Deprotonation of the C–H bond at the 5-position of 2-halo-3-hexylthiophene by LDA followed by metal exchange was carried out in one pot and following addition of nickel catalyst underwent polymerization. One-shot reaction involving deprotonation/transmetalation/ cross coupling polymerization was also examined with manganese(II) chloride and nickel(II) catalyst.Scientific journal - American Chemical Society (ACS), Aug. 2021, Langmuir, 37(34) (34), 10388 - 10393Scientific journal

- Large polystyrene particles stabilized by polyvinylpyrrolidone (PVP) (PSPVP)-core/small silica particles (SiO2)-corona raspberry-like composite particles were successfully prepared by heterocoagulation technique utilizing hydrogen bonding interaction between the pyrrolidone group of PVP and the silanol group of SiO2. The coverage of the SiO2 corona particles on the PSPVP core particle could be controlled by changing the pH of dispersions and the molecular weight of PVP. Moreover, heterocoagulation of large poly(methyl methacrylate) particles stabilized by PVP and small SiO2 particles was also carried out, resulting in formation of raspberry-like composite particles. These results suggested that raspberry-like particles composed of various polymer particles and inorganic particles could be prepared by heterocoagulation technique utilizing hydrogen bonding interaction.Japan Society of Colour Material, 2014, Journal of the Japan Society of Colour Material, 87(10) (10), 356 - 360, Japanese

A facile and novel approach of preparing monodisperse polystyrene (PS) particles having a "cylindrical" shape was discovered. The proposed synthetic method involved dispersion polymerization of the spherical PS particles stirred in a polyvinylpyrrolidone (PVP) aqueous solution for several hours using a magnetic stirrer. In the presence of PVP, the spherical PS particles deformed into cylindrical shapes following stirring; however, the particles did not deform in the absence of PVP. The deformation rate of the particles was affected by the molecular weight of dissolved PVP. This stirring method is not only highly efficient and provides high yield, but is also applicable to other materials such as polymethyl methacrylate (PMMA). Moreover, cylindrical polystyrene particles were applied as a particulate stabilizer to prepare a Pickering emulsion of decane (oil)/water. Unlike the spherical particles that are typically used in Pickering emulsions, the cylindrical particles enhanced the emulsion's stability (up to 1 year). Furthermore, the cylindrical particulate stabilizer enabled a stable emulsion across a wide range of pH. Notably, unique adsorption behavior of the cylindrical particles on an oil droplet was observed, in which the cylindrical particles connected head to head to form a network that acted as a cage around the oil droplet.

After the polymerization, aq. NH3 was subsequently added to the dispersion as a catalyst for sol-gel process, resulting in formation of P(EGDM-MMA) particles with encapsulated SiO2 particles. The sol-gel process proceeded in the water domains and SiO2 particles were formed only inside the capsules. The morphology of SiO2 particles can be controlled by the coalescence behavior of the domains. Moreover, polymer capsules with Pd particles and a Pd complex and the capsules with Au particles were also prepared. Obtained capsules acted as a catalyst for the Suzuki-Miyaura cross coupling and/or reduced reaction of 4-nitrophenol to 4-aminophenol with NaBH4.Competitive research funding

The colloidal structure can be controlled by changing the surface area ratio of the Janus particles such as dendritic and grafting colloidal structures. It was clarified that the distribution of the association number was in a good agreement with the theoretical curve calculated from step-growth polymerization theory. We also demonstrated preparation of colloidal structure using non-spherical particles. We unexpectedly discovered a facile and novel approach to prepare monodisperse polystyrene (PS) particles having a “cylindrical” shape. Notably, unique adsorption behavior of the cylindrical particles on an oil droplet was observed, in which the cylindrical particles connected head to head to form a network (colloidal structure) that acted as a cage around the oil droplet.Competitive research funding

Furthermore, we attempted to apply the structures as micro-sized reactors (femtoreactors) by modification of the encapsulated small particles. In particular, the molecular sieving function of the capsule wall and the structural control of the encapsulated silica particles using the closed femto-space inside the capsule were focused on.

Especially, development of emulsifier-free emulsion polymerization, synthesis of high molecular weight (>10e6), monodisperse polystyrene particles, Syntheses of Janus type nonspherical polymer particles by applying CLRP at the limited locus of polymerization at a particle surface, high performance heat storage microcapsule particles, micrometer-size hydrophilic polymer particles without submicrometer-size byproduct particles, and polymer particles having biosensor functionality have been successfully conducted. These results will contribute to overcoming the long-standing problem and creation of novel functional polymer particles.

We estimated the formation mechanism as following: the encapsulated small particles consisted of poly EGDM, and were formed via precipitation polymerization inside the droplets in competition with formation of the shell. Because the small particles coagulated in the capsules owing to the phase separation of the PS, a toluene/n-hexadecane solution containing an oil-soluble surfactant (polydimethylsiloxane-based macroazoinitiator) was used instead of the LC/PS mixture. Thus, “rattle-like” capsules were successfully prepared using a simple polymerization process. The small particles could move in the capsule and responsed the electric field because the particles having -9 mV of zeta potential.Competitive research funding

Moreover, we showed that anion exchange of the composite particles can be used to modify the properties of only the PIL component of the composite particles. PIL particles with a single-hollow are also prepared by suspension polymerization from monomer droplets consisting of the ionic liquid monomer, ethylene glycol dimethacrylate, and n-butyl acetate. The obtained particles can be changed from hydrophobic to hydrophilic by anion exchange. Moreover, Janus particles with two hemispheres having different stabilizers, a polystyrene (PS) phase stabilized by poly(acrylic acid) and a PMMA phase stabilized by poly(vinyl pyrrolidone), were able to be synthesized. The facile formation of the colloidal chains via hydrogen bonding interaction between different stabilizers were demonstrated.Competitive research funding

Poly(methyl methacrylate) (PMMA) particles containing reduced graphene oxide (rGO) were successfully prepared by miniemulsion polymerization of rGO-dispersed methyl methacrylate (MMA) monomer utilizing the block copolymer as stabilizer to disperse rGO in the monomer phase. The block copolymer was consisted of ionic liquid polymer, poly(1-(2-methacryloyloxyethyl)-3-butylimidazolium bis(trifluoromethanesulfonyl)amide) (P[Mbim][TFSA]) and PMMA, the concept being that the MMA units impart solubility in the monomer droplets whereas the ionic liquid units act as adsorption sites for rGO.

The PPhEMA phase exhibited LCST-type volume-phase transition behavior and separation of IL occurred above the LCST. In contrast, the PMMA phase was swollen with IL separated from the PPhEMA phase. Interestingly, the composite gel particles exhibited similar volume-phase transition behavior in both air and vacuum without leaking of IL from gel particles, which should be free-standing thermosensitive gel particles.Competitive research funding

The composite particles had smooth surfaces and core-shell morphology consisting of PS core and Mg(OH)2 shell having high crystallinity. 2) Micron-sized monodisperse poly(ionic liquid) (PIL) (and composite) particles were prepared by dispersion/emulsion polymerization. Moreover, it confirmed that the obtained particles maintained the properties of the ionic liquid.

- Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), Grant-in-Aid for Scientific Research (A), Kobe University, 2005 - 2007Preparation of capsule particles by self-assembling phase separated polymer method and its applicationWe have proposed the preparation method for micron-sized, cross-linked polystyrene/polydivinylbenzene (PS/PDVB) particles having a single hollow. The mechanism for the hollow polymer particles was based on the Self-assembling of Phase Separated Polymer at an interface with aqueous media, which was named the SaPSeP method. Recently, when the SaPSeP method was applied in the presence of sodium dodecyl sulfate (SDS), it was found that a single hole was formed in the shell of the hollow PS/PDVB composite particles. In this research, in order to clarify such a strange phenomenon, preparations of capsule particles were examined in detail. It was clarified that the phase separation in the droplets in the early stage of the polymerization was one of key factors for the formation of the single hole. Hole was most likely formed as a result of reduced microgel adsorption at oil-water interface domains of high SDS content. Moreover, we succeeded in preparing submicrometer-sized hollow PS particles, microcapsules containing curing agent for epoxy resin, and PDVB particles with encapsulated titanium oxide or n-hexadecane (HD)by micro-suspension polymerization utilizing the SaPSeP method. HD is useful for heat storage materials. The encapsulation of HD has many advantages that provide large heat transfer area and control the volume change of the heat storage materials. However, there were some problems in encapsulated HD such as decrease of the heat of solidification and supercooling. In this research, the problem in the application of the polymer particles with encapsulated HD as heat storage material was improved by the copolymerization of hydrophilic acrylic monomer. This seems to be based on that the copolymerizations of hydrophilic monomer enhance the phase separation of copolymer chains and HD, eventually resulting in the complete isolation of the HD core from the polymer shell.

Such particles are used as microcapsules, weight-saving or thermal insulation agents, and are applied to hiding or opacifying agents in coating and molding compositions because of their high light-scattering ability. We had succeeded in preparing micron-sized, monodisperse, crosslinking polymer particles having a single hollow at the center by seeded polymerization. Similar hollow polymer particles were produced by suspension polymerization for divinylbenzene (DVB)/toluene droplets dissolving polystyrene though they were polydisperse. The formation of the hollow structure is based on the self- assembling of phase separated polymer at the interface of the droplet. The method is named the Self-assembling of Phase Separated Polymer (SaPSeP) method. In this research, in order to clarify the formation mechanism of hollow particles by the SaPSeP method in more detail, the effects of phase separation of PDVB in the droplets, viscosity within the droplet and its size on the formation of the hollow structure were discussed. The phase separation in the early stage was required point for the formation of the hollow structure. Since the viscosity in the droplet is low at the low conversion, the PDVB can move and adsorb at the interface of the droplet. The mobility of PDVB microgels after the phase separation in polymerizing droplet was important factor for the formation of the hollow structure. The SaPSeP method was developed to produce composite particles encapsulating hinokitiol or magnetite. Moreover, the method was applied to the polyaddition reaction in a suspension system. The polyaddition reaction system satisfied the required conditions for the preparation of hollow particle by the SaPSeP method. In actual, cured epoxy resin particles having one hollow at the center were successfully prepared after evaporation of toluene.

The use of scCO_2 as medium for polymerizations has several potential advantages : low cost, low toxicily, eases of medium removal and recycling, and marked variations of solubility power, viscosity and polarity by relatively small changes in temperature and pressure without altering medium composition. The papers describing the dispersion polymerization of vinyl monomers such as methyl methacrylate (MMA) and styrene in scCO_2 have been published in the past eight years. Some fluorinated polymers and poly(dimethylsiloxane) (PDMS)-based polymers have been identified as being soluble in CO_2 or CO_2-philic and have been used as colloidal stabilizers, and there has been increasing interest on the colloidal stabilizers which are effective in scCO_2. In general, PDMS-based polymers may have advantages over fluorinated polymers from the viewpoints that PDMS-based polymers are much less expensive and their solubility in conventional organic solvents makes the characterization of the products obtained easy. In this research, PMMA particles could be produced by dispersion polymerization of MMA in scCO_2 using PDMS-based azoinitiator as inistab (initiator + stabilizer). Production of PMMA particles by the dispersion polymerization of MMA in scCO_2 in the presence of amino propyl terminated PDMS as colloidal stabilizer was also succeeded. Moreover, polydivinylbiphenyl particles were produced by precipitation polymerization of divinylbiphenyl without any stabilizer in scCO_2 at ca. 30 MPa for 24 h at 65℃. The effects of initiation rate of polymerization on the conversion, the fluidity of powder, the degree of coagulation/ the amount of low molecular weight by-products, and the amount of vinyl groups in the particles were examined.
