【摘要】 利用辉光放电技术,将C₂H₂/CO₂/H₂的等离子体聚合物沉积处理聚氯乙烯商品膜表面进行改性。用红外光声光谱和扫描电子显微镜分析观察了等离子体改性的聚氯乙烯膜的结构和表面形态。测量了改性膜的水接触角,计算了它们的表面自由能,界面自由能以及表面功,从而研究了改性膜的亲水性。同时,利用热重分析仪（TGA）研究了改性膜的热稳定性。更多还原

【Abstract】 In glow discharge, conventional polyvinylchloride （PVC） membrane is modified by depositing plasma polymer of C₂H₂/CO₂ /H₂ onto PVC membrane surface. The morphology and structure of the modified membrane are observed by TEM amd FTIR Photoacoustic Spectra. The static contact angle of the membrane is measured. From the contact angle values, the interracial free energy between the membrane and water, surface free energy of the membrane and adhesive work are calculated. Moreover, the thermalstability of modified PVC film is also investigated.更多还原
