Abstract:In order to solve the problem of environmental pollution caused by petroleum-based plastics， the development of bioplastics with degradable properties is a research hotspot. Owing to the characteristics of biodegradability， biocompatibility and antibacterial， natural polysaccharides are ideal raw materials for the preparation of biodegradable plastics. Natural polymer polysaccharides are difficult to directly utilize because of high crystallinity. Meanwhile， the structure of polyhydroxy caused polysaccharide-based materials easily hygroscopic in high humidity environment， resulting in structural damage and performance reduction. Therefore， it is still a great challenge to prepare polysaccharide-based plastics with high performance. The research progress of polysaccharide-based plastics prepared from cellulose， chitin， and starch via molecular engineering and compounding strategies were introduced in this paper， which provided a theoretical basis and research ideas for the development of polysaccharide-based biodegradable plastics in the future.
