基于液/冰界面自组装制备高分子通透结构有序多孔薄膜的研究

Ordered porous films have important applications in making photonic crystals, filtration membranes, cell culturing substrates, catalyst supports, templates, superhydrophobic surfaces, microlens arrays, and colloid sorting. As the applications of ordered porous films developed, how to fabricate highly permeable ordered porous membranes with dynamically controlled pore size facilely and economically is becoming one of the hottest areas.In this proposal,we will establish a systematic method to prepare highly permeable ordered porous polymer membranes using controllable self-assembly on liquid/ice interface. The unique interface assembly process will be used to fabricate higly permeable ordered proprous structures dynamically, economically and facilely. The preparation mechanisms and properties of the highly permeable ordered porous membranes will be studied, and the applications in making high performance microfiltration membranes and templating materials with ordered microstructures will be investigated.
