摘　　要：采用熔融共混法制备了聚丙烯/聚醚改性聚硅氧烷共混薄膜。并用衰减全反射红外光谱、接触角测试仪、扫描电子显微镜、熔融指数仪和热重分析仪对共混薄膜进行了表征。结果表明:聚醚改性聚硅氧烷扩散迁移到PP表面;当改性剂加入量为10份时,共混物薄膜表面的水接触角接近0°,不影响材料的加工性能;加入1份增容剂PP-g-PEG可以明显提高改性剂的时效性;不同的接触介质对改性效果有重要影响。Blend films of PP/polyether-polysiloxane were prepared by melt blending, and characterized by ATR-IR, contact angle instrument, scanning electron microscopy, melt index instrument and TGA. The results show that Polyether-polysiloxane diffuse and migrate to the surface of blend films; the contact angle of water of the blend films with 10 phr modifier is close to 0°, the processing properties of materials have not been affected; the timeliness of modifier with 1 phr compatibilizer PP-g-PEG could be significantly improved; and different mediums have an important effect on the modification effect.
