  • Fabrication of multifunctional BN fine fibers by force spinning method
    Patent number: 11859315
    Abstract: A method of preparing hexagonal boron nitride (h-BN) fibers includes mixing polyvinylpyrrolidone (PVP) and boron oxide (B2O3) to form a polymer precursor or mixing PVP and ammonia borane (BH3NH3) to form the polymer precursor. The method includes forcespinning the polymer precursor to form fibers of the polymer precursor, curing the fibers to form polymer fibers, and pyrolyzing the polymer fibers to form the h-BN fibers.
