Boron nitride nanotubes (BNNTs) feature outstanding thermal conductivity and are, therefore, an excellent candidate for thermal interface materials (TIM). Since BNNTs are also electrically insulating, they are especially suitable for TIM applications in microelectronics. We have recently developed the first method to completely remove h-BN impurities from BNNTs without doing damage to the tubes, which we demonstrate using characterization techniques based on X-ray diffraction and Raman spectroscopy. Furthermore, our procedure has an extremely high yield, virtually not losing any material. Using our purified, high-quality BNNTs we make polymer nanocomposites with significantly enhanced thermal conductivity and mechanical performance. We developed several processing methods for BNNT/polymer nanocomposites and found that they have a dramatic impact on the observed thermal and structural properties.
