摘要
用溶液共混法制备聚乙烯醇/壳聚糖(PVA/CS)共混膜,对共混膜进行了IR、DSC表征和吸水率、透光率、力学性能等进行测定。结果表明:PVA与CS分子链间在共混膜中有一定的相互作用,相容性好;CS的引入有利于改善PVA的吸水性、透光率和综合力学性能,但热稳定性有所降低。
The blend film of poly （vinyl alcohol） （PVA）/chitosan （CS） has been prepared. Infrared spectroscopy （IR） and DSC has been applied to research the film and water absorption, light transmittance, mechanical properties of the film have been tested. As a result, there were some interaction between PVA and chitosan, which showed that introduction of chitoasn was helpful to improve light transmittance and mechanical property, and decrease water absorption of PVA.
