The effects of surface-structural change of HDPE (high-density polyethylene) induced by exposure to plasmas of various gases on the conduction characteristics are studied. Fourier-transform-infrared spectra were obtained by the attenuated total reflection method, while electron-spin-resonance spectra were obtained at X-band. Conduction current (DC, 10 min value) and thermal-pulse current (TPC) were also measured. It is concluded that many transvinylenes and free radicals remain on the surface of high-density polyethylene treated by argon or hydrogen plasma, while in the case of oxygen plasma treatment, many carbonyls and only a few free radicals remain. The surface layer treated by hydrogen plasma or the successive exposure to oxygen or ozone impede electrons and holes from being injected into the polyethylene bulk beyond the surface layer.
