▎ 摘　　要

NOVELTY - Flexible conductive material is formed by grafting epoxy group on graphene surface as connecting group and covalently bonding cellulose to form flexible conductive material. USE - Flexible conductive material used in textile field (claimed). ADVANTAGE - The flexible conductive material has improved fastness of graphene material on cellulose surface, increased conductivity of cellulose fiber, high durability, good thermal performance, soft hand feel, and good strength, and does not influence the softness and comfort of fiber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of flexible conductive material comprising preparing reaction-type graphene oxide material by dispersing graphene oxide in reaction medium, ultrasonically dispersing, adding epoxysilane, where mass ratio of graphene oxide and epoxysilane is 1:1-6, under nitrogen protection, reacting for 4-24 hours at 40-120 degrees C, and preparing silanized graphene oxide material, and preparing flexible conductive material by putting cellulose raw material into water at bath ratio of 1:3-30 at room temperature, adding reaction-type graphene oxide material, ultrasonically dispersing, adding sodium sulfate (Na2SO4) at 20-50 g/L water, raising the temperature to 60-90 degrees C, adding sodium carbonate (Na2CO3) at 10-30 g/L water, keeping the temperature for 30-90 minutes, taking out the product, washing with hot water, cold water and soap, drying, reducing at 110-130 degrees C for 3-5 hours and obtaining the product.
