  • 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.

  • Compositions and methods associated with intercalating and exfoliating a sample
    Patent number: 10000419
    Abstract: Compositions and methods associated with intercalating and exfoliating a sample are described herein. For example, of a method may include mixing the sample with intercalation materials. The intercalation materials are then intercalated into the sample to obtain a sample intercalated with the intercalation materials. The intercalated sample can then be exfoliated to produce an exfoliated sample.
