▎ 摘　　要

NOVELTY - Graphene cotton composite fiber comprises 55-75 %mass cotton fiber, 2-12 %mass first adhesive layer, 15-35 %mass graphene layer and 1.5-8.5 %mass second adhesive layer from inside to outside. USE - As graphene cotton composite fiber. ADVANTAGE - The composite fiber reduces the redox processing steps of graphene, and improves the adhesion of graphene/cotton composite fiber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing the graphene-cotton composite fiber comprising impregnating cotton fibers in a sodium hydroxide solution, reacting for 20-50 minutes under ultrasonic action, taking out the cotton fibers for water washing until the temperature is 50-80 degrees C, reacting for 40-70 minutes, adding graphene into the solution, adding the end capping agent under the ultrasonic treatment, reacting for 20-40 minutes at 65-75 degrees C, taking out the composite fibers and drying.
