纳米SiO2改性玉米淀粉/聚乙烯醇复合薄膜研究
The Study on Corn Starch / Polyvinyl Alcohol Composite Films Modified by Nano-SiO2
摘要
Abstract
To improve the physical properties, the technological conditions of com starch and polyvinyl alcohol composite film modified by nano-SidO2 are studied through single-factor experiments and orthogonal test, using tensile strength, break age elongation, transmittance and water absorption rate as indexes. The experimental results showed that the concentration of nano-SiO2, variety and concentration of dispersant and pH of film liquid all can affect the properties of the films. The suitable process parameters: the optimum concentration of nano-SiO2 was 2.0%; the best dispersant was polyacrylamide, and its optimal concentration was 1.5%; the best pH of film liquid was 5.0.关键词
