Boron nitride nanotubes (BNNTs) as one dimensional nanofiller similar to carbon nanotubes (CNTs) offer complimentary properties to CNTs and are more favorably compatible with various polymer matrices. This could make BNNTs a preferred candidate for reinforcing polymer composites when electrical conductivity is not required but better thermal management, transparency, neutron absorption and electrical insulation are desired. Due to the one dimensional hollow fibrous structure, BNNTs are useful in reinforcement of fibers for high performance textiles applications. Here we report our recent advances in 1) the integration of BNNTs into polyacrylonitrile (PAN) in solution, 2) electrospinning into two-dimensional matt (2D matt) and 3) the process of their stabilization and carbonization.
