▎ 摘　　要

NOVELTY - A heat storage and anti-icing material has an energy density of 150-250 Wh/kg, droplet contact angle of 140-160 degrees , and a surface shear force of 3-5 kPa, and is prepared by dispersing graphene oxide in 30-50 parts mass deionized water, adjusting pH to 8-10 using sodium carbonate, adding sodium borohydride, reacting at 80-90 degrees C for 2-4 hours, reducing, dissolving 2-3 parts mass azobenzene and 2-3 parts mass sodium nitrate in deionized water at room temperature, adding 10-12 parts mass aqueous solution of hydrochloric acid, reacting, obtaining diazonium salt, adding diazonium salt to reduced graphene, obtaining an azobenzene/graphene composite material, dispersing in ethanol, impregnating porous alumina template with resultant solution, drying, solidifying, and removing alumina template using an alkali. The concentration of aqueous solution of hydrochloric acid is 1-2 mol/L. The mass ratio of diazonium salt and reduced graphene is (30-60):(80-100). USE - Heat storage and anti-icing material. ADVANTAGE - The heat storage and anti-icing material has excellent hydrophobic performance, anti-icing effect and storage performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the heat storage and anti-icing material.
