摘 要：Porous polymeric films represent a new class of materials that have attracted both industrial and academic *** past years,porous materials have been widely investigated for a variety of applications such as molecular and protein separation,catalysis,and ultralow dielectric devices. Recently,block copolymers have been receiving an increasing attention as a candidate for an ideal template due to their registered ***,we report two novel methods to prepare nanoporous and microporous polymer films by supercritical fluids foaming and breath figure technique,*** films appear with an average diameter ranging from 15 to 30 nm processed by an scCO process at a pressure from 8 to 20 *** polymer films have highly ordered pore arrays,working as template to align ZnO and carbon nanotubes.
