| Abstract: | 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. |
