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

本研究通过对相应共聚物膜的SCAT制备了5种具有可聚合端基和亲水或疏水侧链作为锚点的新型二维表面改性剂，通过1H-NMR和GPC谱证实了表面改性剂的结构（图1）。选择具有良好成膜能力和良好渗透性的两种聚合物（PSPA和PDPA）作为基础聚合物膜，将2D表面改性剂的甲醇溶液与基础聚合物的甲苯溶液混合，浇铸在Teflon片材上，得到基础聚合物表面的超分子2D聚合物（Ⅱ）。在室温下，将所得到的膜浸入1,2-乙二胺中48小时，得到基底聚合物上的二维聚合物（Ⅲ）。

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).
