摘要:

采用溶液流延法,将不同比例的壳聚糖(CS)、聚乙烯醇(PVA)、明胶(GEL)溶液混合均匀后,倾倒在有机玻璃板上流延成膜,制备不同系列CS/PVA/GEL复合薄膜,并通过红外分析、紫外分析和表面接触角测定等手段对其进行表征,同时,对CS/PVA/GEL复合薄膜的热稳定性能、燃烧特性、透氧性能、保鲜、力学等性能进行了测试。结果表明:当CS、PVA、GEL按照10/3/7质量比共混时,制得的共混膜综合性能最好。

Abstract:

Chitosan (CS) was mixed uniformly with poly(vinyl alcohol) (PVA) and gelatin (GEL) at different mass ratios, and the resulting solution was dumped onto a plexiglass plate by using a solution⁃casting method to obtain a series of CS/PVA/GEL blend films. The structure of the blend films was characterized by infrared spectrogram analysis, ultraviolet spectrum analysis, water contact angle, and so on. Their thermal stability, flame retardancy, oxygen permeability, preservation, mechanical properties were investigated. The results indicated that the blend films exhibited the best comprehensive performance at a CS/PVA/GEL mass ratio of 10/3/7.

Key words: barrier effect, flame retardant, film, chitosan
