摘　　要：通过磺化反应改善聚乙烯(PE)非织薄膜的亲水性,考察了时间、温度、物料配比等条件对磺化反应的影响,并用红外光谱(FT-IR)、X射线能量色散谱(EDS)及扫描电镜(SEM)对产物进行了表征,同时对PE非织薄膜的亲水性和力学性能进行了测定。结果表明:通过氯磺酸磺化可以将—SO3H基团引入PE大分子,磺化后的PE链段互相聚集无序堆砌形成微小颗粒;PE非织薄膜的断裂强度随磺化反应程度的增加而下降。The hydrophilic property of PE non-woven thin film was improved by using sulphuration. The effect of time,temperature and the ratio of reactants on the property of hydrophilic of PEwere illustrated in detail. The introduction of --SO3H to sulphurated PE was characterized by FT-IRspectroscopy and energy dispersive X ray （EDS）. The result shows that not only the hydrophilicproperty of PE non-woven film is dramatically improved but also the original stretch intensity of PEnon-woven film well retained when the sulphuration temperature is 80 ℃ and time is 1.5 h.
