摘要：

Highly ordered microporous films containing polyolefin segment were successfully fabricated via the breath-figure (BF) method using well-defined polymethylene-h-polystyrene (PM-h-PS) diblock copolymers in CS(2) under a static humid condition. The effects of molecular weight of diblock copolymers, relative humid, fabrication method and temperature on the morphology of film are investigated. The honeycomb porous films with different pore size (1.2-2.5 mu m) were obtained by using PM-h-PS with different PM : PS ratio. The thick (7 mu m) and thin (2 mu m) films were fabricated via a different process. The film with a pothole-like structure was fabricated when using PM-h-PS with the shortest PS segment. Smaller satellite pores were found to surround the regular micropores of honeycomb films when the BF process was carried out at 28 degrees C.
