Abstract Scope |
Advanced materials with high thermal conductivity while electrically insulating are needed for thermal management in high-power microelectronics. Boron nitride nanotubes (BNNTs) feature outstanding performance in both respects, thus being highly promising for such applications. We developed a technique to produce highly purified BNNTs in a scalable manner to further enhance their performance. We further developed spectroscopic methods to detect BNNT purity. Rather than simply embedding BNNTs into a matrix material, we are working with 3-dimensional networks of strongly connected tubes for enhanced thermal transport. Compared to composites made of disconnected tubes of the same volume concentration, this approach leads to enhanced thermal and mechanical properties. Based on the network topology we have detected directional thermal conductivity, which has great potential for advanced thermal applications. |
