Abstract

Abstract: High density polyethylene (HDPE) treated with plasma gases (including Ar, N₂, O₂ and air) in various conditions (including treatment power, treatment time and treatment pressure) was studied by ESR.
It was found that the radicals on the surface of HDPE, resulting from such a treatment, were rather stable and their intensity of ESR signal increased with the treatment power as well as the treatment time, but only slightly changed with treatment pressure. It was evidenced that the ultraviolet effect on the radicals of the surface of HDPE changed with conditions of plasma treatment. Their hyperfine interaction in the spectra of HDPE was interpreted.

Key words: Plasma, High-density polyethylene, Electron spin resonance
