Abstract

The self-assembly of 1,2,3-triazole and ionic 1,2,3-triazolium "clicked" poly(3-hexylthiophene)-b-poly(methylmethacrylate) (P3HT-b-PMMA) rod-coil diblock copolymers was used to fabricate honeycomb-patterned porous films via "breath figure" templating. The surface and inner morphologies of the honeycomb films can be both controlled by either ionizing the 1,2,3-triazole linker or changing the counter-ion nature.

摘要

通过“呼吸图案”模板法，利用1,2,3 - 三唑和离子型1,2,3 - 三唑鎓“点击”聚（3 - 己基噻吩）-b-聚（甲基丙烯酸甲酯）（P3HT-b-PMMA）棒 - 线圈二嵌段共聚物的自组装来制备蜂窝状多孔膜。蜂窝状膜的表面和内部形态可以通过使1,2,3 - 三唑连接基离子化或改变抗衡离子性质来控制。
