Abstract：

The emulsions of acrylate and vinyl triethoxysilane (VTES) were prepared by emulsion polymerization. The structure of copolymer was characterized by ATR-FTIR. The effect of ratio of VTES to acrylate on dynamic viscosity of emulsions, degree of cross linking, hydrophilicity and swelling performance of membranes were investigated, diffusion coefficients of membranes in water and ethanol were obtained according to the swelling experiments. The FTIR results indicated that organic functional silanes had been copolymerized with acrylate monomer thoroughly. With increasing ratio of VTES to acrylate, dynamic viscosity of emulsion increased, degree of cross linking and contact angle of membranes increased. Increasing concentration of ethanol or sorption temperature can improve the degree of swelling of membranes. Diffusion coefficient of membrane of 0.15 VTES loading (VTES/acrylate) in pure ethanol was 0.02309(10-4m2•s-1), the diffusion coefficient of membrane of 0.02 0.15 VTES loading (VTES/acrylate) in pure water was 0.02357 (10-4m2•s-1).
