▎ 摘　　要

NOVELTY - High-performance graphene composite nano cellulose comprises nano cellulose with the graphene material, where the graphene-like material in situ with nano cellulose, the graphene composite nano cellulose, the content of graphene-like material is less than 20 wt.%, further 10 wt.% or less, and further between 0.5-5 wt.%. USE - The nano cellulose is useful in medicine, environmental protection, food packaging, composite material (claimed). ADVANTAGE - The nano cellulose can keep high the content of graphene particles still dispersed uniformly, less agglomerated particles produced, far infrared property, excellent toughness and hot water resistance and antistatic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene composite nano cellulose comprising (i) mixing cellulose, graphene-like material and de-ionized water ultrasonic dispersing, grinding to obtain suspension, (ii) heating the suspension ultrasonic, centrifuging, freezing and drying and shaping to obtain graphene composite nano cellulose, preferably, the suspension, the concentration of the cellulose is 1-10 wt.%.
