Abstract

The invention relates to a high-strength and tough biomass-based membrane material and a preparation process. The membrane material is composed of maleic anhydride-modified chitosan, O-acylated chitosan, biomass-based 1,4-butanediisocyanate, and bio-based 1 , 6-hexanediol, four-arm polyethylene glycol propionaldehyde, and eight-arm hydroxybutyl cage polysilsesquioxane are used as raw materials to form a film through solution casting. The biomass composite material has a simple processing technology, has excellent strength and toughness, can be degraded, and can be applied to packaging and industrial fields that require high-strength and tough films.

Description

technical field [0001] The invention relates to a preparation method of a biomass-based membrane material, in particular to a preparation method of a membrane material with excellent strength and toughness, degradability and certain antibacterial properties. Background technique [0002] The proportion of membrane materials in materials is very large, and most membrane materials are still made of plastic materials. On the one hand, although plastic materials have excellent mechanical properties and wide applicability, they are derived from petroleum products and cannot be degraded. Environmental pollution has also caused waste of resources. On the other hand, it is very difficult for plastic materials to achieve certain functions due to their single groups. It is currently becoming a challenge to find alternative materials with excellent performance, functionality and renewable materials. The top priority of research in the field of materials; especially in the field of cast...
