微孔聚合物薄膜是一种极具吸引力的材料，在电子、光子学和生物技术领域具有潜在的应用前景。微孔聚合物薄膜的材料应用需要具有化学和热稳定性。除了通过传统的光刻法制备之外，我们还报道了通过利用小水滴在两亲性共聚物溶液上的冷凝的方法来制备蜂窝状图案的多孔聚合物薄膜。在这里，我们展示了热和化学稳定材料聚酰亚胺的蜂窝状图案微孔薄膜的制备。水模板辅助的蜂窝结构由聚酰胺酸和二烷基铵盐的聚离子络合物形成。薄膜的孔径大小由聚合物溶液的浇注量控制。图案化的聚离子复合膜通过简单的化学处理转变成聚酰亚胺，并保持多孔结构。制备了自支撑微孔聚酰亚胺薄膜。蜂窝结构纤维...
Microporous polymer films are attractive materials with potential application in the fields of electronics, photonics, and biotechnology. Chemical and thermal stabilities of the microporous polymer films are required for their materials application. Besides preparation by conventional photolithography, we have reported that honeycomb-patterned porous polymer films are prepared by a method utilizing the condensation of small water droplets on solutions of amphiphilic copolymers. Here, we show preparation of honeycomb-patterned microporous films of a thermally and chemically stable material, polyimide. A water-template-assisted honeycomb structure was formed from a polyion complex of polyamic acids and dialkylammonium salt. The pore size of films was controlled by the casting volume of polymer solution. The patterned polyion complex film converted into polyimide by simple chemical treatment, keeping the porous structure. Self-supporting microporous polyimide films are fabricated. The honeycomb-structured fi...
