NOVELTY - Composite phase change material comprises 50-80 wt.% phase change material, 10-30 wt.% thermally conductive material, 0-10 wt.% flame retardant, 0-15 wt.% polymer, and 0-5 wt.% antioxidant. USE - As composite phase change material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the composite phase change material, which involves compressing a thermally conductive material to a predefined density, mixing or absorbing or infiltrating a phase change material in the compressed thermally conductive material, and coating the composite of phase change material absorbed thermally conductive material with a flame retardant slurry or resin, or mixing or absorbing or infiltrating phase change material with thermally conductive material, compressing the mixture of the thermally conductive material and the phase change material, and coating the compressed mixture of the thermally conductive material and the phase change material with a flame retardant slurry or resin.
