研究了水溶液阴极常压空气辉光放电(APGD)对丙纶薄膜和坯布表面的作用。以氯化钾、溴化钾和碘化钾水溶液为阴极。采用接触角测量、表面自由能计算、傅立叶变换红外衰减全反射(FT-IR/ATR)分析和毛细管上升高度等方法对PP的表面性能进行了表征。PP表面处理后，观察到酯、酮、羧基中的羟基、C=O基团，不饱和酮、醛中的C=O基团。改性工艺不仅可以改善织物的润湿性，还可以实现部分卟啉在PP表面的固定化。
We investigated the action of an atmospheric pressure air glow discharge (APGD) with aqueous electrolyte cathode onto the surface of polypropylene films and grey cotton fabric. Aqueous solutions of KCl, KBr and KI were utilized as a cathode. The surface properties of PP were characterized by contact angle measurement followed by surface free energy calculation, Fourier Transform Infrared by Attenuated Total Reflectance (FT-IR/ATR) analysis and height of water capillary rise for fabric. After treating PP surface, we observed OH-groups, C=O groups in ester, ketone and carboxyl groups, C=O groups in unsaturated ketones and aldehydes. Modification processes were able to improve the wettability of fabric as well as to accomplish the immobilization of some porphyrins onto PP surface.
