▎ 摘　　要

NOVELTY - Preparing graphene nanosheet material dispersed in a natural polysaccharide with high efficiency comprises mixing natural polysaccharides and solid graphite, placing the mixture in an oxygen atmosphere and carrying out mechanical grinding, to obtain monolayer and/or multilayer graphene nanosheet complex with thickness of 0.33-9 nm dispersed in natural polysaccharide. USE - The method is useful for preparing graphene nanosheet material dispersed in natural polysaccharide with high efficiency (claimed). ADVANTAGE - The material has van der Waals forces and CH- pi interactions between the graphene nanosheets and the natural polysaccharide interface, chemical reaction and graphene peeling efficiency of 10-80%.
