▎ 摘　　要

NOVELTY - Composite material comprises microcapsules containing a phase change material and having a surface layer coated with a polymer material, a curable acrylic resin matrix photopolymerized with acrylic groups grafted onto the surface layer, and a heat dissipation material mixed with the acrylic resin matrix. The heat dissipation material is regularly arranged by a photomasking film patterned during the photopolymerization process of the curable acrylic resin matrix. The microcapsules are in irregularly mixed state with the curable acrylic resin matrix. USE - Used as composite material. ADVANTAGE - The composite material: has high thermal conductivity with improved heat dissipation performance; and produces high efficiency with small amount by regularly arranging heat dissipation fillers inside the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing the composite material, comprising preparing microcapsules containing a phase change material and having a surface layer coated with a polymer material, substituting a functional group on the surface of the polymer material with an acryl group, photopolymerizing the surface acrylic group of the polymer material and the acrylic monomer, where the acrylic monomer is in a mixed state with the heat dissipation material, and the heat dissipation material is patterned using a photomasking film, and simultaneously the microcapsule is in a state of being irregularly mixed with the curable acrylic resin matrix during photopolymerization step.
