摘要: 用纳米SiOx对壳聚糖涂膜进行改性,并对所形成的涂膜进行表征,结果表明,复合膜中壳聚糖与SiOx微粒间存在强烈的氢键相互作用,改性后壳聚糖膜的性能在保鲜效果、持水性、透光率和力学性能等指标上得到改善和提高。

Abstract: Chitosan were modified and characterized by adding nano-SiOx .The results showed that a great deal of hydrogen bonds formed among chitosan composite films and large amount of hydroxyl groups occurred on the surface of silicon dioxide noparticles. And also it was found that the keeping effect, optical trasmittance, water permeability, mechanical properties and the likes of the films were improved and increased obviously.
