Efficient heat removal via thermal management materials has become one of the most critical challenges in the development of modern microelectronic devices. However, previously reported polymer composites exhibit limited enhancement of thermal conductivity, even when highly loaded with thermally conductive fillers, because of the lack of efficient heat transfer pathways. Herein, we report
The theoretical thermal conductivity of silicon carbide is very high, reaching 270W/m•K. However since the ratio of surface energy to interfacial energy of SiC ceramic materials is low, that is, the grain boundary energy is high, it is difficult to produce high purity and dense SiC ceramics by conventional sintering methods.
