壳聚糖复合海绵材料的制备及性能

Preparation and Performance of Compound Chitosan-based Sponge

制备的壳聚糖-明胶-海藻酸钠-聚乙烯醇(1∶1∶1∶0.5,w/w)复合海绵材料具有多孔性结构,在去离子水中的吸水率、相对保湿率和透气率分别为31.75g水/g、29.14%和43.20%。

The compound chitosan-based sponge with the weight ratio of chitosan-gelatin-sodium alginate-PVA of 1 ： 1 ： 1 ： 0.5 was prepared for wound dressing. The product had porous structure, and the moisture-adsorption rate in deionized water, moisture-retention rate and air permeability rate were 31.75g H2O/g, 29.14 % and 43.20 %, respectively.
