Composites of Oxidized Boron Carbonitride Nanotubes with Polyaniline: Preparation and Conductivity Studies

Five precursors of boron carbonitride nanotubes with different B/N ratios were synthesized. Oxidation with nitric acid afforded oxidized boron carbonitride nanotubes (o-BCNNTs), with which composites with polyaniline (o-BCNNTs/PANI) were prepared by in situ oxidative polymerization. For one of the o-BCNNTs, composites were synthesized with a varying amount of the nanotube (up to 30 wt %), while for the rest the nanotube content was maintained at 30 wt % in each case. It has been found that the conductivity of the oxidized boron carbonitride nanotubes decreases with an increasing BIN ratio and that of the composites increases with an increasing percentage of the o-BCNNTs.
