摘要
用溶液共混法制备PVA与壳聚糖共混膜,用红外光谱对共混膜进行了表征,并对膜的吸水率、透光率和力学性能进行测试。结果表明,共混膜中PVA分子链与壳聚糖分子链有一定的相互作用,壳聚糖的引入有利于改善PVA的透光性和降低其吸水率。
The blend film of PVA and chitosan has been prepared . IR( infrared spectroscopy) has been applied to research the film. Water absorption, light transmittance and mechanical properties of the film have been tested. As a result , there were some interaction between PVA and chitosan , which showed that introduction of chitosa-nias was helpful to improve light transmittance and mechanical property , and decrease water absorption of PVA.
