Hexagonal boron nitride (h-BN) fibers...
Hexagonal boron nitride (h-BN) fibers should enable the preparation of composites similar to "carbon/carbon" materials but suitable for higher-temperature applications. The thermolysis of symmetric and asymmetric alkylaminoborazines to polyborazines is reported by P. Miele and co-workers, along with their subsequent processing to polyborazine filaments and h-BN fibers (March 18; Adv. Funct. Mater. 2002, 12, 228-234).
