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

本研究通过共聚膜的SCAT反应合成了五种新型的具有可聚合端基和亲水或疏水支链的新型二维表面改性剂，其结构经1H-核磁共振和凝胶渗透色谱确证。选用成膜性好、渗透性好的两种聚合物(PSPA和PDPA)作为基膜，将2D表面改性剂的甲醇溶液与基聚合物的甲苯溶液共混，浇铸在特氟龙片上，得到基聚合物(Ⅱ)表面的超分子2D聚合物，然后在1，2-乙二胺中常温浸泡48h，得到基聚合物(Ⅲ)上的2D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).
