▎ 摘　　要

NOVELTY - Preparing highly oriented layered graphene aerogel phase change composite material comprises (i) hydrothermally reacting the graphene oxide suspension by heating in sections to obtain reduced graphene hydrogel, (ii) pre-freezing the reduced graphene hydrogel, (iii) vacuum freeze-drying the reduced graphene hydrogel pre-frozen processed to obtain a layered aerogel material, (iv) subjecting the layered aerogel material to high-temperature carbonization or graphitization, and (v) subjecting the layered aerogel material to high-temperature carbonization or graphitization and combining with the phase change material through vacuum impregnation. USE - The method is useful for preparing highly oriented layered graphene aerogel phase change composite material. ADVANTAGE - The composite material has excellent directional thermal conductivity, high energy storage characteristics and good anti-leakage performance, and has broad application prospects in the field of phase change energy storage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for highly oriented layered graphene aerogel phase change composite material obtained by the method as mentioned above.
