▎ 摘  要

NOVELTY - Preparing graphene thermally conductive phase change material with isolated structure involves adding 1 pts. wt. graphene oxide in 500-10,000 pts. wt. deionized water, ultrasonically dispersing to prepare graphene oxide dispersion liquid. The 450-1350 pts. wt. of 10.0-30.0 milligram surfactant aqueous solution is added into the obtained graphene oxide dispersion liquid and ultrasonically dispersed to obtain the modified graphene oxide dispersion liquid. The 50-300 pts. wt. phase change material is added to modified graphene oxide dispersion liquid, heating to melt the phase change material. USE - Method for preparing graphene thermally conductive phase change material with isolated structure (claimed). DETAILED DESCRIPTION - Preparing graphene thermally conductive phase change material with isolated structure involves adding 1 pts. wt. graphene oxide in 500-10,000 pts. wt. deionized water, ultrasonically dispersing to prepare graphene oxide dispersion liquid. The 450-1350 pts. wt. of 10.0-30.0 milligram surfactant aqueous solution is added into the obtained graphene oxide dispersion liquid and ultrasonically dispersed to obtain the modified graphene oxide dispersion liquid. The 50-300 pts. wt. phase change material is added to modified graphene oxide dispersion liquid, heating to melt the phase change material, and then adding the solution to high-shearing dispersion for emulsifying to obtain phase change material emulsion. The 0.1-1 pts. wt. reducing agent is added to the phase change material emulsion under stirring condition, refluxed and reacted for 5 minutes to 24 hours to obtain a core-shell structure of phase change material graphite. The core-shell structure of phase change material graphite is subjected to hot press molding to prepare the graphene thermally conductive phase change material with isolated structure.
