摘要

Microporous films with honeycomb structures have received great interest in recent years, which may be applied in chemical sensors, optical apparatus, scafflold for catalysis, biology and tissue engineering, etc. Recently, a new method utilizing water droplets as templates to form ordered porous films, first described by Fran?ois et al. aroused much attention. They cast the solution of polyparaphenylene in carbon disulfide onto a substrate in a high humid atmosphere, after the solvent and water droplets evaporated completely, a film with regular honeycomb pores was obtained, and they believed that the water droplets condensed at the surface of the solution acted as the templates. Many polymer materials were used to prepare honeycomb-like films, such as rod-coil block copolymer, star polymer, comb polymer, dendritic copolymers, amphiphilic copolymer, etc. All these materials contained hydrophilic structures in their molecules, which could stabilize the water droplets that condensed on the surface of the polymer solution. Recent years’ research showed that some linear polymers, without any polar end group in their molecule structures, also led to ordered porous films. Peng et al. got honeycomb films by using polystyrene (PS) with linear structure, and Xu et al. constructed regular porous structures by linear polysulfone (PSF).
