| Research Abstract |
1. An general method was developed to chemically activate BN nanotubes. The activated BN nantubes can be further modified based on hydroxyl group chemistry.
2. Various highly thermo-conductive insulating polymeric composites based on BN nanotubes were fabricated. The matrixes were epoxy, polystyrene, PMMA etc. A method was developed to embed high fraction of BN nanotubes in matrix. By this technique, more than 30 wt.% BN nanotubes can be embedded, and the thermal conductivity of matrixes can be improved up to 21-fold.
3. As fundamental research, for the first time, the density and specific heat capacity of BN nanotubes were measured, which is useful for prediction of properties of BN nanotube composites.
