▎ 摘　　要

NOVELTY - A nano-storage thermoregulated fiber comprises a comb-shaped polymer phase-change material and thermally conductive particles. The thermally conductive particles are graphene, nano-silver, nano-titanium dioxide and/or nano-silicon. The comb-shaped polymer phase-change material comprises group (I), group (II) and group (III). The group (I) is polyacrylonitrile acrylic acid grafted with n-alkanol or polyethylene glycol grafted polyacrylonitrile acrylate. The group (II) comprises polyacrylonitrile acrylic acid grafted with two different molecular weights of n-alkanol or polyacrylonitrile acrylic acid grafted with two different molecular weights polyethylene glycol or polyacrylonitrile acrylic acid grafted with n-alkanol. USE - Nano-storage thermoregulated fiber. ADVANTAGE - The nano-storage thermoregulated fiber has excellent suitability, heat stability and quick heat storage and release performance. DETAILED DESCRIPTION - A nano-storage thermoregulated fiber comprises a comb-shaped polymer phase-change material and 2-10 wt.% thermally conductive particles. The thermally conductive particles are graphene, nano-silver, nano-titanium dioxide and/or nano-silicon. The comb-shaped polymer phase-change material comprises group (I), group (II) and group (III). The group (I) is 20-80 %mass polyacrylonitrile acrylic acid grafted with n-alkanol or polyethylene glycol grafted polyacrylonitrile acrylate. The group (II) comprises polyacrylonitrile acrylic acid grafted with two different molecular weights of n-alkanol or polyacrylonitrile acrylic acid grafted with two different molecular weights polyethylene glycol or polyacrylonitrile acrylic acid grafted with n-alkanol. The group (III) comprises polyacrylonitrile acrylic acid grafted with n-alkanol of different molecular weights, polyethylene glycol grafted polyacrylonitrile acrylate of different molecular weights, polyacrylonitrile acrylic acid grafted with n-alkanol or polyethylene glycol grafted polyacrylonitrile acrylate. An INDEPENDENT CLAIM is included for preparation method of nano-storage thermoregulated fiber, which involves adding comb-shaped polymer phase-change material and thermally conductive particles to solvent to prepare spinning solution, electrostatic spinning the spinning solution and curing.
