    本研究では種々のナノシート材料を支持膜上に積層することによって超薄型有機溶剤ろ過膜を作製し,2-Dチャネル内での有機溶剤透過メカニズムの解明および溶剤―溶質,溶剤―溶剤分離の検証を行う.有機架橋分子を層間に導入し,2-Dチャネル内での化学的相互作用を評価することで積層構造を精密に制御し,透過性や阻止性に寄与する因子を明らかにする.これにより革新的な高透過性ナノシート積層型有機溶剤ろ過膜を実現し,膜工学分野における新たな基礎学理を構築する. R5年度の研究では,GOナノシート積層膜のチャネル構造の制御を目的として,GO層間における金属有機構造体(MOF)ナノシートの形成,またGO層間への二次元物質であるポルフィリン分子の導入に関する検討を行った. 1. MOF-GO複合積層膜は,GO層間におけるZnOナノ粒子のソルボサーマル合成とGO層間の制限された2-Dチャネル内でのZnOからZn-TCPPへのin-situ変換を利用した2段階の方法で作製した.ZnOの合成時間や担持量を最適化することにより,2-Dチャネル内でZn-TCPPの優先配向が示され,水分子の透過パスが短くなり,19.0 L m-2 h-1 bar -1という高い透水性と高いアニオン性色素阻止率を達成した.またメタノールなどアルコール系溶媒への応用も可能であることを確認した. 2. GO積層膜へのポルフィリン(TPP: 5,10,15,20-Tetraphenylporphyrin)分子の導入によるOSN性能への影響について検討した.GO+TPP積層膜において,X線回折測定により積層構造に由来する回折ピークが観察され,TPP修飾により層間隔がわずかに増加することが確認された.またOSN性能を評価したところ,メタノール透過性が増加し,メタノール中のビタミンB12の阻止率は90%以上に向上した.TPP修飾により層間隔の拡大による流量の増加と,2Dチャネル内に部分的な立体障害が生まれたことによる分子ふるい効果の向上によるものと考えられる.
