▎ 摘　　要

NOVELTY - Modified graphene/nanocellulose conductive functional coating comprises 9-anthracene carboxylic acid modified multilayer graphene, absolute dry nano cellulose and water, where the mass ratio of 9-anthracene carboxylic acid modified multilayer graphene, absolute dry nano cellulose and water is 1:0.025-0.1:1-10. USE - The coating is useful for preparing food paper with heat preservation and heating functions (claimed). ADVANTAGE - The coating has high efficiency, low cost; utilizes modified graphene having more carboxy groups on the surface and raw materials having good adhesion properties; can form conductive coating with excellent dispersibility with nanocellulose; and prepares food paper for food heating under energized conditions without harming food. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the modified graphene/nanocellulose conductive functional coating comprising mixing 9-anthracene carboxylic acid modified multilayer graphene, absolute dry nano cellulose and water and ultrasonically dispersing to obtain the coating.
