▎ 摘　　要

NOVELTY - Graphene functionalized high-performance cashmere products comprises cashmere fibers and graphene sheets coated on the outer surface of the cashmere fibers, the graphene sheet is a single-layer or few-layer graphene, its particle size is less than 10 mu m, compared with ordinary cashmere products, the surface temperature in the sun can be increased by 10-30 degrees C. USE - Used as graphene functionalized high-performance cashmere products. ADVANTAGE - The graphene functionalized high-performance cashmere product has good antistatic, anti-ultraviolet and antibacterial properties, also has self-heating function under sunlight. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene functionalized cashmere product with high performance comprising (1) adding 50 g graphene oxide powder in 10 l pure water, ultrasonically processing for 20-60 minutes, diluting with pure water to obtain a concentration of 0.005-0.5% of uniformly dispersed graphene oxide solution, (2) adding 1-50 surfactant in 50 kg solvent, dissolving completely, adding 10 kg pre-soaking washed cashmere product for 10-30 minutes and taking out and using pure water to wash, naturally air drying or drying under the temperature of 40-65 degrees C, cashmere product get surface with positive charge (3) adding the cashmere product obtained in the step (2) into 100 l by the step (1) to obtain the graphene oxide solution for reacting for 5-60 minutes, taking out from the solution with pure water for washing for more than 3 in the pure water of 80-100 degrees C and reacting for 3-20 minutes to obtain the cashmere product of graphene oxide modified, (4) adding 10-50 g ascorbic acid in 100 l pure water, dissolving completely, adding into the solution obtained in the step (3) of the graphene oxide modified by cashmere product, and reacting for 20-60 minutes, taking out the sample, using pure water for washing for more than 3 under the temperature of 85-100 degrees C, naturally drying or under the temperature of 40-65 degrees C and drying for 12-72 hours to obtain the graphite alkene functionalized cashmere product with high performance.
