The unusually broad physical and chemical property window of ionic liquids allows for a wide range of applications, which gives rise to the recent spring-up of ionic liquid-based functional materials. Via solvothermal copolymerization of a monomeric ionic liquid and divinylbenzene in the presence of a tissue paper in autoclave, we fabricated a flexible porous polymer/paper hybrid membrane. The surface areas of the hybrid membranes depend on the weight fraction of the copolymer impregnated inside the tissue paper. The as-prepared hybrid membrane shows controlled surface wettability in terms of ethanol wetting and ethanol removal by harsh drying condition. This unique property provides the hybrid membrane with switchable oil/water separation function, thus of practical values for real life application.
离子液体具有异常宽广的物理和化学性质窗口，这使得它们在众多领域都有广泛的应用，这也促使了基于离子液体的功能材料的迅速发展。我们通过在高压釜中，使单体离子液体和二乙烯基苯进行溶剂热共聚反应，同时使用纸巾作为模板，制备了一种柔性多孔聚合物/纸杂化膜。杂化膜的表面积取决于浸渍在纸巾内部的共聚物的重量分数。所制备的杂化膜在乙醇润湿和苛刻干燥条件下乙醇去除方面表现出可控的表面润湿性。这种独特的性质赋予了杂化膜可切换的油水分离功能，因此在实际应用中具有实用价值。
