▎ 摘　　要

NOVELTY - Preparing graphene aerogel phase change composite material comprises mixing a graphene oxide solution with expanded graphite to form a uniform dispersion liquid, freezing the dispersion liquid in a liquid nitrogen atmosphere, obtaining an ice-containing graphene oxide/expanded graphite anisotropic mixed hydrogel, freezing the graphene oxide/expanded graphite anisotropic mixed hydrogel containing ice in a freeze dryer to obtain a graphene oxide/expanded graphite anisotropic aerogel, placing the graphene oxide/expanded graphite anisotropic aerogel in an oven, heating to obtain reduced graphene oxides/expanded graphite anisotropic mixed aerogel, placing the reduced graphene oxides/ expanded graphite anisotropic mixed aerogel into the melted paraffin, waiting for the paraffin to absorb to saturation, allowing to stand for cooling naturally to obtain reduced graphene oxides/ expanded graphite mixed aerogel phase change composite material. USE - The method is useful for preparing graphene aerogel phase change composite material. ADVANTAGE - The composite material: has oriented thermal conductivity and good stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene aerogel phase change composite material with oriented thermal conductivity.
