제목 Development of through-plane thermal conducting pathway via using of hybrid Al2O3/h-BN fillers in polymer composites
초록 Heat dissipation polymer composites consists of polymer with high thermal conductivity filler such as carbon or ceramic (Al2O3, AlN, h-BN) material. One of the ceramic materials, h-BN is a promising filler material because of high thermal conductivity with insulate property. however in thermal interface materials and gap filler application, it is hard to apply as a filler because of its anisotropic thermal conductivity (∥: 600 W/mK, ⊥: 30 W/mK).
In this study, in order to fabricate 3-dimensional thermal path and optimize through-plane thermal conductivity, composites were prepared using spherical Al2O3 and h-BN based on silicone rubber. structure of composite is designed to surround the Al2O3 of h-BN in order to dissipate heat well in vertical direction, and optimized thermal conductivity is obtained by controlling the content of Al2O3 and h-BN.
