Abstract
Self-assembled honeycomb-patterned porous polymer films are fabricated by breath figure method. The The porous film of polystyrene, polyimide and polysulfone are made. Pores with a few hundred nanometers to several micrometers have been generated by controlling various process parameters, such as solution concentration, substrate temperature and humidity. The numerical calculations of water cluster growth on the polymer surface are carried out. The relationship between pore size and time, and the method of getting smaller pore size is suggested.
