The surface modification of polystyrene films via selective aggregation of polyether silicone oil(PSO) on their surfaces was studied.Because of the surface activity of the silicone oil chain segments,the(selective) migration of PSO was greatly increased.Owing to the good hydrophilicity of the polyether chain segments,the surface free energy(γ) of the blends was enhanced by 180%,and the polar portion of its γ increased nine times.Attenuated total reflectance Fourier transform infrared spectroscopy(ATR-FTIR) and contact angle measurement were used to detect the surface structure and surface properties.It was found that the influence of contact medium on the selective migration of polyether silicone oil was important.Glass substrate can induce more polyether chain segments to segregate at the polystyrene/substrate interface and air can induce more silicon oil chain segments to the polymer surface.
