NOVELTY - Graphene-modified disodium hydrogen phosphate dodecahydrate hydrated phase-change thermal storage material comprises 95-98 pts. wt. disodium hydrogen phosphate dodecahydrate, 1-3 pts. wt. graphene, 0.5-2 pts. wt. nucleating agent, 1-3 pts. wt. thickening agent and 0.2-2 pts. wt. anti-caking agent. USE - The hydrated phase-change thermal storage material is useful as solar energy storage and thermal management of electronic devices. ADVANTAGE - The hydrated phase-change thermal storage material: has high phase change exothermic enthalpy value, and excellent anti-caking performance and high stability and simple preparation process; and is convenient for packaging and production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-modified disodium hydrogen phosphate dodecahydrate hydrated phase change thermal storage material comprising (1) mixing disodium hydrogen phosphate dodecahydrate, graphene and nucleating agent, refining into powder, and melting the powder to obtain melting graphene-modified disodium hydrogen phosphate dodecahydrate, and (2) melting and mixing the graphene-modified disodium hydrogen phosphate dodecahydrate with thickening agent and anti-caking agent to obtain colloidal mixture as final product.
