中文摘要:
      目的 以壳聚糖、 聚乙烯醇为基材, 对壳聚糖膜共混改性, 制得一种性能优良的绿色环保包装材料。方法 用溶液共混法制备壳聚糖-聚乙烯醇共混膜, 用红外光谱、 扫描电镜对其进行表征并对其力学性能、 透气性、 透光率、 雾度等进行测试。结果 研究表明, 共混时2种组分之间发生了分子间作用力, 两组分的共混比例(体积比)为40∶60或60∶40时所制备的共混膜表面平滑, 两组分有很好的相容性。结论 所制备的聚壳聚糖-乙烯醇共混膜有很好的成膜性能、 力学性能和透气性能等, 在食品、 药品等领域有广泛的应用前景和价值。
英文摘要:
      With chitosan and polyvinyl alcohol (PVA) as the components, a new type of environmental-friendly packaging material with excellent properties was prepared. This blend film of chitosan/PVA was prepared by solution mixing. The structure was studied by infrared spectroscope and scanning electron microscopy. And the mechanical properties, gas permeability, optical transmittance and haze of the films were tested. The results showed that there was some strong interaction between the two components. When the blend ratio of the two components was 60∶40 or 40∶60 (volume ratio), the membrane surface of the prepared blend film was smooth and the compatibility was very good. The prepared blend films of chitosan/PVA had great film-forming property, mechanical property and gas permeability, which can be widely applied in the fields of food, medicine and so on.
