Abstract: The surface modification of polytetrafluoroethylene film by exposuring to argon plasma was carried out and the structure of the surface was investigated by x-ray photoelectron spectroscopy(XPS). The broad, overlaping C1s peak in XPS spectrum was considered to be formed from 284.6(CH), 286.6(CO), 287.9(C = O), 289.0(CF)and 292.3 eV(CF2). It is found that, along with oxygen, nitrogen was also introduced into the surface structure of PTFE upon plasma treatment.

Key words: polytetrafluooethylene, plasma treatment, XPS, surface structure
