摘　　要：研究了成膜基材对有机硅聚合物-聚甲基丙烯酸甲酯溶液共混物薄膜表面性能的影响。利用表面能、红外和DSC等手段研究了有机硅聚合物/丙烯酸酯聚合物共混物溶液在不同基材上通过溶剂挥发成膜的表面共混组成。结果表明,以铁为基材时,含硅丙烯酸酯共聚物在成膜时会自发地在聚合物膜与空气界面富集;以聚四氟乙烯为基材时,含硅组分易于向基材界面富集;而以玻璃为基材时,含硅组分易向空气界面迁移。The effect of the substrate on the surface properties of organosilicon polymer and acrylate polymer blend films was investigated. The surface free energy, IR and DSC were used to detect the blend films and its composition at the surface side and the bottom side. Various substrates were employed such as glass, stainless sted and PTFE. When the glass and steel are film-formation substrate the component of organosilicon polymer enrich to the surfaces. When the PTFE is film-formation substrate the component of organosilicon polymer enrich to the bottom.
