Aluminum hydroxide-CNT hybrid material for synergizing the thermal conductivity of alumina sphere/thermoplastic polyurethane composite with minimal increase of electrical conductivity |
| 초록 |
Multi-walled carbon nanotube (CNT) was hybridized with aluminum hydroxide utilizing aluminum trichloride hexahydrate as a precursor to prepare a filler that can be utilized for a thermally conductive yet electrically insulative polymer composite. The thermal conductivity of an alumina sphere/thermoplastic polyurethane (TPU) mixture (100 parts) was enhanced 2 to 3-fold when 5 parts of this hybrid material (Al-CNT hybrid) was added as a synergizer for thermal conduction. This enhancement was better than that by CNT. Moreover, the electrical conductivity increase due to the added Al-CNT hybrid was marginal, whereas the increase was striking when CNT itself was added instead. In addition, the embrittling of polymer composite was somewhat alleviated when the Al-CNT hybrid was used as a thermal conductivity enhancer instead of CNT due to the somewhat coarser dispersion in the TPU matrix. |
