摘要

利用预辐射接枝技术，在聚乙烯膜上接枝苯乙烯磺酸钠（SSS）、苯乙烯三甲基氯化铵（VBTAC）等具有离子交换性能的单体，研制出了具有抗菌性能的离子交换膜，并且使得原先憎水性的基膜转变为亲水性较好的膜。通过实验，掌握了膜的接枝工艺，并对膜的接枝过程、结构特征、理化性能有了较多的了解。从各个角度对膜的亲水性能作了定量研究，提出了水合数与表面自由能的计算方法。对几种膜的抗菌性能进行了评价，确定了VBTAC膜作为抗菌性包装膜的潜力。

Abstract

Two kinds of monomer (SSS and VBTAC) containing ion-exchange groups were cografted with HEMA onto HDPE membrane respectively by pre-irradiation grafting. Thus we obtained ion-exchange membranes with anti-bacteria function. The grafted membranes had good hydrophilicity compared with the hydrophobicity of the base film. The research was focus on 3-point: (1) Study the process of the grafting reaction, structure of the grafted membranes, chemical and physical properties of the grafted membranes. (2) Quantitative study of the hydrophilicity of the grafted membranes, evaluate the hydration number and surface free energy of the membranes. (3) Study the antibacterial activity of the grafted membranes. The antibacterial ability of the VBTAC membrane was so good that it would be fit for an antibacterial material.
