NOVELTY - The preparation method of graphene thermal conductivity reinforced phase change energy storage material involves heating mixture of capric acid and lauryl alcohol, ultrasonically stirring until the mixture is completely melted, adding cetyltrimethylammonium bromide-reduced graphene oxide, ultrasonically stirring and mixing, naturally cooling to room temperature, and grinding into powder to obtain cetyltrimethylammonium bromide-reduced graphene oxide/capric acid-lauryl alcohol composite material. USE - Preparation method of graphene thermal conductivity reinforced phase change energy storage material (claimed). ADVANTAGE - The preparation method of graphene thermal conductivity reinforced phase change energy storage material with improved dispersibility, thermal conductivity, uniformity, and stability.
