常压辉光放电等离子体研究进展及聚合物表面改性

Research progress of atmospheric pressure glow discharge plasma and polymer surface modification

综述了常压辉光放电等离子体(APGDP)的产生机理及研究进展。介绍了难以产生稳定的APGDP 是由于辉光放电容易向细丝放电和弧光放电过渡,其解决措施是选择合适的介质板材料、电极间距、电源电压及频率、气体成分等。指出APGDP对化纤聚合物表面改性的效果与聚合物的分子结构、等离子体气体、介质板材料等因素有关,且改性效果具有时效性,要根据聚合物的分子结构选择合适的等离子体。

The research progress and generation mechanism of atmospheric pressure glow discharge plasma （APGDP） were reviewed. APGDP was difficult to be acquired due to the initiation of glow-to-filaments transition or glow-to-are transition in discharge region. This problem can be solved by selecting proper medium materials, electrode distance, power voltage and frequency, gas composition etc. The polymer surface modification using APGDP was correlated with the factors including polymer molecular structure, plasma gas and medium material. The modification efficiency provided by APGDP would be vanished along with the time, so the reasonable plasma gas should be used according to the molecular structure of polymers.
