摘　　要：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°。Chlorosulfonie acid as sulfonating agent, 1,2 - dichloroethane as solvent, the effects of the reaction temperature, reaction time, and the amount ratio of HSO3Cl/C2 H4Cl2 on the PP hydrophilic were investigated by orthogonal experiment. The static contact angle of water,SEM characterization and FTIR were measured. The results showed that the contact angle could reduced to as low as 60°, the improvement of PP＇ s hydrophilieity was obvious.
