新規２Ｄ両親媒性化合物を用いた汎用高分子膜の表面改質による高性能酸素分離膜の開発

本研究通过对相应的共聚物膜进行SCAT反应，制备了5种新型的具有可聚合端基和亲水或疏水侧链的二维表面改性剂，并通过1H-NMR和GPC光谱对表面改性剂的结构进行了表征。两种聚合物选择成膜性好、渗透性好的聚苯乙烯（PSPA）和聚偏二氯乙烯（PDPA）作为聚合物基膜，将二维表面改性剂的甲醇溶液和基膜的甲苯溶液共混后浇铸在聚四氟乙烯片上，得到二维超分子聚合物基膜（Ⅱ），将所得基膜浸入1，2-乙二胺在室温下反应48 h，得到了在基体聚合物（Ⅲ）上的二维聚合物。

In this research, five kinds of novel 2D surface modifiers with polymerizable end groups and hydrophilic or hydrophobic side chains that will act as an anchor were prepared by SCAT of the corresponding copolymer membranes, structure of the surface modifiers (Chart 1) were confirmed by 1H-NMR and GPC spectra. Two kinds of polymers(PSPA and PDPA) which showed a perfect membrane forming ability and also good permeability were selected as the base polymer membranes, the methanol solution of the 2D surface modifier and toluene solution of the base polymer were blended and casted on the Teflon sheet to get the supramolecular 2D polymer on the surface of the base polymer(Ⅱ), and this resulting membrane were immersing into the 1,2-ethanediamine for 48h at room tempreture to get the 2D polymer on the base polymer(Ⅲ).
