摘　　要：对紫外光接枝表面改性的聚四氟乙烯（ＰＴＦＥ）薄膜进行了Ｘ射线光电子能谱的研究。结果表明，ＰＴＦＥ表面在预光照阶段发生ＣＦ键的断裂，产生活性中心；在接枝反应阶段，ＰＴＦＥ表面的ＣＦ键继续受紫外光照射而发生断裂，氟原子脱落。ESCA study was performed on films of photoinduced surface grafted polytetrafluoroethylene.The formation of grafting copolymer was verified by XPS. The results show that the preirradiation make the CF bond broken and the surface of PTFE film was activated. The CF bond was broken further and reacted with acrylic acid in the following step of ultravioletirradiation graft polymerization.
