Abstract
Disclosed herein are boron nitride/boron nitride nanotube composite fibers and methods of making and use thereof. For example, disclosed herein are methods of making a boron nitride/boron nitride nanotube composite fiber by spinning a mixture comprising a plurality of boron nitride nanotubes, a polymeric boron nitride precursor, a polymer, and a solvent to form precursor fibers having a first average outer diameter. The methods further comprise drawing the precursor fibers to form drawn fibers having a second average outer diameter that is less than the first average outer diameter. The methods further comprise heating the drawn fibers while the drawn fibers are under tension to substantially remove the polymer and to substantially convert the polymeric boron nitride precursor to boron nitride, thereby forming the composite fiber. Also disclosed herein are composite fibers made by any of the methods disclosed herein.
