NOVELTY - Preparation of graphene-cotton fibers involves dispersing graphene solution having concentration of 2-6 g/L at 60 degrees C, ultrasonically processing for 30 minutes, adding 5 g dopamine and 15 g tea polyphenol, stirring, mixing for 30 minutes, leaving the mixture still for 2 minutes, adding 2 kg cotton cellulose fibers, stirring for 20 minutes, filtering, pressing resultant fibers, crushing, aging, filtering, defoaming, spinning, cutting and drying. USE - Preparation of graphene-cotton fibers (claimed). ADVANTAGE - The method enables simple preparation of graphene-cotton fibers having excellent moisture permeability, thermal conductivity, antibacterial property, high-temperature flame retardance, far-infrared ray resistance, deodorizing effect, thermal insulation property, antistatic property, UV resistance, moisture-absorption property, softness and strength, with high yield.
