纳米粒子对多糖基复合膜微观结构的影响研究进展

Review of the Influence of Nanoparticles on the Microstructure of Polysaccharide Based Blend Films

多糖基复合膜具有均匀、透明和可降解等特点,成为生物可降解膜领域的热点研究内容。研究发现,纳米粒子与多糖溶液共混能形成复杂的成膜液,干燥成膜后,膜的原生微观结构改变,进而改善复合膜的力学、阻隔等性能。本文简述了淀粉膜、壳聚糖膜和魔芋葡甘聚糖膜三种多糖膜的微观结构及组分分子间的相互作用,并对纳米粒子与多糖共混成膜后,复合膜微观结构和理化性能的变化进行了重点阐述,以为多糖基复合膜微观结构设计与膜性能调控研究等提供参考。

The polysaccharide based blend films have the characteristics of uniformity,transparency and degradability.It has become a hot research direction in the field of biodegradable film.Studies have found that mixing nanoparticles with polysaccharide solution could form a complex film-forming solution.After film formation,the original microstructure of the film changed,thereby improving the mechanical and barrier properties of the blend film.In this paper,the microstructure and molecular interaction in starch film,chitosan film and konjac glucomannan film were reviewed.The changes in microstructure and physicochemical properties of the films blended with nanoparticles and polysaccharides were emphatically described,in order to provide reference for the microstructure design and film performance control of the polysaccharide based blend films.
