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 C_1s 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.
