▎ 摘　　要

NOVELTY - Cellulose based flexible conductive paper comprises plant fiber slurry and graphene prepared by papermaking technology. USE - The paper is useful in electromagnetic shielding material, surface heating material, advanced energy and electrochemical materials and sensing and braking material (claimed). ADVANTAGE - The paper has good biocompatibility and flexibility, and is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing cellulose based flexible conductive paper comprising either (i) homogeneously mixing graphene and vegetable fiber pulp for papermaking, and then adding into paper with retention aid filter to obtain mixed slurry paper, (ii) copying the pre-mixed slurry obtained in step (i) to obtain handwritten copy, and (iii) coating the hand-drawn sheet obtained in step (ii) with micro or nano cellulose, or calendering the dosing sheet obtained in step (ii), where in step (i), addition amount of papermaking retention aid is 0.03-0.5 wt.% based on total mass of plant fiber slurry of graphene and absolute dry pulp; or (i) adding graphene and ultrashort polypropylene cellulose to water, and then adding surfactant into obtain chemical fiber slurry, (ii) mixing paper fiber slurry for papermaking and the chemical fiber slurry of step (i) to obtain papermaking mixture slurry, (iii) copying the paper before the papermaking mixture of the step (ii) to obtain handwritten sheet, and (iv) drying the handflake sheet of step (iii).
