| 摘 要： | 目的以壳聚糖(chitosan)、木薯淀粉和聚乙烯醇(PVA)为基础成膜原料,探究纳米SiO2改性木薯淀粉/PVA/壳聚糖薄膜的制备工艺过程。方法以薄膜断裂伸长率、抗张强度、透光率和吸水率为评判标准,在单因子试验基础上,设计L9(34)正交试验,研究纳米SiO2含量、分散剂十二烷基苯磺酸含量、膜液pH值等3个因素对纳米SiO2改性木薯淀粉/聚乙烯醇/壳聚糖薄膜性能的影响。结果得出了制备纳米SiO2改性木薯淀粉/PVA/壳聚糖薄膜的最佳工艺参数,纳米SiO2质量分数为2.0%、十二烷基苯磺酸钠质量分数为2.0%、膜液pH值为3.0,3个因素对改性薄膜性能的影响程度大小排序为分散剂含量纳米SiO2含量pH值。结论获得了纳米SiO2改性木薯淀粉/PVA/壳聚糖薄膜的最佳生产工艺参数。

| Abstract: | The work aims to study the preparation technology process of Nano-SiO2 modified cassava starch/ PVA/chitosan film, with chitosan, cassava starch and polyvinyl alcohol (PVA) as basic film-forming materials. With elongation at break, tensile strength, transmittance and water absorption as evaluation index, based on single factor test, the influences of the Nano-SiO2 content, the content of dispersant SDBS and the pH value of casing solution on properties of Nano-SiO2 modified cassava starch/PVA/chitosan films were studied through the design of L9 (34) orthogonal experiment. The best process parameters for the preparation of Nano-SiO2 modified cassava starch/PVA/chitosan film were obtained. The mass fraction of Nano-SiO2 was 2.0%, the mass fraction of SDBS was 2.0%, and the pH value of casting solution was 3.0. The ranking of three factors affecting the modified film performance was dispersant content>Nano-SiO2 content>pH value. The best production process parameters of Nano-SiO2 modified cassava starch/PVA/chitosan films are obtained. |
