抗菌剂壳聚糖在聚氨酯微孔膜中的应用研究

The Application of Chitosan in Polvurethane Microporous Films as Anti-bacterial Agent

本实验利用质量分数为2.5%的乙二醇做致孔剂,采用湿法成膜的方法制备聚氨酯微孔膜。在此基础上,本文分别研究了壳聚糖作抗菌剂时对聚氨酯微孔膜各项性能的影响。研究结果表明:壳聚糖不仅具有良好的致空性能,同时也具有良好的抗菌性能,很好的改善了聚氨酯微孔膜的综合性能。

In this paper, the polyurethane microporous membrane was prepared by wet filming method with 2.5% （in mass） as porogen. Based on the above work, the influence of chitosan on the polyurethane microporous membrane was studied. The results of the study indicated that the chitosan showed not only reliable porogen properties, but also out- standing anti-bacterial properties.
