NOVELTY - Light-to-heat conversion, thermal storage and temperature-adjusting cellulose fiber comprises 0.45 to 1.91 wt.% graphene, 0.47 to 0.95 wt.% zirconium carbide, and 4.7 to 9.5 wt.% phase change energy storage microcapsules. USE - Light-to-heat conversion, thermal storage and temperature-adjusting cellulose fiber. ADVANTAGE - The light-to-heat conversion, thermal storage and temperature-adjusting cellulose fiber has temperature of 9.7-29.9 degrees C higher, and the visible light absorption rate is increased by 30-55%, fiber enthalpy is 8.1-15.5J / g, and the fiber phase transition temperature is 25.4-36.6 degrees C. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing light-to-heat conversion, thermal storage and temperature-adjusting cellulose fibers, which involves preparing graphene dispersion system, preparing phase-change energy storage microcapsule slurry containing photothermal material-zirconium carbide, preparing functional cellulose spinning solution, and spinning.
