Boron nitride based polymer composites as thermal dissipation materials : effects of surface modification, size control, and delamination |
| 초록 |
Heat sink materials are widely used for thermal radiation material such as semiconductor and LED because of life-time reduction by exothermic reaction. Interfacial problem at ceramic/polymer composite is a key issue for heat sink materials with high thermal conductivity, K because thermal losses occur at the interface. Here we used hexagonal boron nitride (h-BN) for a ceramic filler because it has high K and high surface area when exfoliated. In order to reduce interfacial resistance BN has been surface-modified using silanes. We will present surface modification schemes using multi-silanes and effects of filler size and distribution for maximizing K of the composite. The silane modification was confirmed by FTIR. Delamination of h-BN was confirmed by TEM and Raman scattering. Thermal conductivity of the composite was analyzed by laser flash method. |
