摘要: 本文研究了不同处理条件(处理功率、处理时间和处理压力)下等离子体气体(Ar、N2、O2和空气等)对高密度聚乙烯表面处理产生的自由基的ESR谱。
我们观察到等离子体处理产生的自由基是相当稳定的,它的ESR信号强度随处理功率和处理时间增加而增加。但处理压力对它影响不大。我们证明了紫外线对高密度聚乙烯表面产生自由基作用随处理条件而变化。并初步解释了谱的超精细相互作用。

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.
