ABSTRACT£ºThe block copolymer of PS-b-PHFMA was synthesized by atom transfer radical polymerization, which was dissolved in selective solvent. Along with the evaporation of the selective solvent, the block copolymer would assemble into micelles by itself, which were core-shell structure. At the end of the evaporation, the block copolymer would change to be super-hydrophobic films, which possessed "grain structure". This method had introduced fluorine into the copolymer successfully. The contact angle and sliding angle were measured as 152.3º and 8.2º respectively, which showed an excellent super-hydrophobic property. Çë´ó¼ÒÐÞ¸ÄһϠÎÒµÄÕªÒª |
