摘要

以丙烯酸和苯乙烯为单体，聚乙烯膜为基体，利用过氧化预辐照接枝技术，研制出一种具有亲水-疏水平衡结构的新型抗凝血渗析膜。探讨了单体组成对膜性能的影响。结果表明：当丙烯酸和苯乙烯单体组成为1：1（体积比）时，接枝膜具有较好的机械性能。与未接枝膜相比，抗凝血性提高了约30倍，渗析性提高约10倍。

Abstract

A new type of antithrombogenic polymeric dialytic membrane with a hydrophilic-hydrophobic microphase structure was prepared by grafting acrylic acid and styrene into polyethylene films, using peroxidation preirradiation technique. Various ratios of monomers influencing on properties of the grafted films were examined. Experimental results showed that the grafted films have superior mechanic strength, and their antithrombogenicity and permeability were 30 and 10 times higher than that of the ungrafted films respectively on condition of the volume ratio 1:1 (styrene vs acrylic acid).
