Y. Taru et al., STUDY OF THE SURFACE OF PLASMA-TREATED PE FILMS BY MEANS OF XPS-1S AND VALENCE-BAND SPECTRA, Nippon kagaku kaishi, (8), 1993, pp. 991-994
Bond-structure of hydrocarbon and density of polar groups at the surfa
ce region of argon and oxygen plasma-treated polyethylene (Ar-PE, 02-P
E) were investigated by means of the XPS 1 s and valence band spectra.
In case of An-PE, branching and cross-linking hydrocarbon units occur
first, then reaction of radical survived with oxygen and/or nitrogen
results in polar groups at the film surface. In case Of 02-PE, oxidati
on of the polymer film is prior to branching and cross-linking.
