▎ 摘　　要

NOVELTY - Modified graphene/carbon nano-tube/nano-ellulose conductive heating coating comprises multi-layer graphene modified by 1-naphthoic acid, carbon nano-tubes, dried nano-cellulose and water in a mass ratio of 1:0.05-0.2:0.025-0.1:1-10. USE - The coating is useful in preparing the conductive heating food wrap paper (claimed) and preparing constant temperature conductive heating layer with an arbitrary target temperature in the range of 60-90 degrees C. ADVANTAGE - The coating has high heating performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the coating, comprising mixing 1-naphthoic acid modified multilayer graphene, carbon nano-tubes, dried nano-cellulose and water in a mass ratio of 1:0.05-0.2:0.025-0.1:1-10, ultrasonically dispersing and stirring.
