Electrically Aligned-Al2O3 Flakes Reinforced Polymer Compositesfor High Thermal Conductivity |
| 초록 |
The current trend in microelectronic components requires thermally conductive but electrically insulating ceramic particle reinforced polymer composites for electronic packaging. In this study, thermal conductivity of aluminum oxide (Al2O3) reinforced polymer composites was investigated. In order to enhance thermal conductivity of the composite, flake-like Al2O3 particles in the polymer matrix were electrically aligned to the direction parallel to the heat flow by application of DC electric fields. The effects of filler content, applied electric field on the microstructure, crystal structure and thermal conductivity of the composite were examined. As the electric field was applied, the occurrence of the microstructural changes, which is anisotropic alignment of Al2O3 flakes in the matrix, contributed to improvement of thermal conductivity of the composites by increasing thermal conducting path. |
