聚四氟乙烯微胞孔膜的结构和表征

The Structure and Characteristics of Microcelluar Polytetraflouroethylene Porous Membrances

使用多种方法制备了聚四氟乙烯微胞孔膜，以扫描电子显微镜、化学分析电子能谱及鼓泡测孔径法表征，结果表明，通过等离子体聚合，乙烯－四氟乙烯接枝沉淀于基体膜上的方法能可控地获得良好的表征。

The paper expounds the physico-chemical properties of microcellular foams and polytetraflouroethylene, micro-and ultramicro-cellular polytetraflouroethylene porous membrances which were prepared in different ways, and characterized by scanning electron microscope, electron spectroscopy for chemical analysis and blowing bubble method. The results show that the substrate membrance through flow coating combines plasma polymerization with ethylene. The membrance is easy to control and has good characteristics.
