通过正交试验,以氯磺酸为磺化剂,对聚丙烯膜进行磺化反应处理,分析反应温度、反应时间、以及氯磺酸与1,2-二氯乙烷配比对PP亲水性的影响。进行水滴静态接触角的测量以及红外、扫描电镜的表征。实验结果表明:亲水性改善效果明显,接触角最低为60°。 Through orthogonal experiment, using chlorosulfonic acid as sulfonating agent, the polypropylene membrane was sulfonated, the reaction temperature, reaction time, and the ratio of chlorosulfonic acid and 1,2-dichloroethane to PP hydrophilic Sexual effects. Static contact angle measurement of water droplets and infrared, scanning electron microscopy characterization. The experimental results show that the hydrophilic effect is obvious and the minimum contact angle is 60 °.
