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 but electrically insulative polymer composite. The thermal conductivity of alumina sphere/thermoplastic polyurethane (TPU) mixture (100 parts) was enhanced 2~3 fold when 5 parts of this hybrid materials (Al-CNT hybrid) was added as a synergizer for thermal conduction. This enhancement was better than that by CNT itself. Moreover, the electrical conductivity increase by 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 Al-CNT hybrid was used as a thermal conductivity enhancer instead of CNT itself due to somewhat coarser dispersion in TPU matrix.
