Abstract：
 An osmotic composite film for desulfurizing gasoline is basically prepared from dimethyl silicone rubber and trifluoropropyl silicone rubber through dissolving the polyacrylonitrile in solvent, preparing substrate, treating it by surfactant, dissolving said two kinds of silicone rubber in solvent, adding surfactant, coating it on said substrate and heat treating. It can selectively separate the high-S material from low-S material.
