Abstract: A process for preparing a phase change microcapsule having a thermally conductive shell is introduced. The thermal conductivity of the encapsulation materials for the phase change microcapsules is increased by adding thermally conductive nano-materials. The vinylsilane compound is polymerized with the acrylic monomer to form the copolymer first, and then the thermally conductive inorganic material is added. Thereafter, the phase change microcapsule having the phase change material as the core and the thermally conductive material-containing copolymer as the shell is prepared. The polar functional groups on the surface of the thermally conductive inorganic material condense with the vinylsilane compound to form chemical bonding, thereby substantially increasing the compatibility between the thermally conductive inorganic material and the copolymer.
