Abstract

A modified boron nitride nanotube (BNNT) comprising pendant hydroxyl (OH) and amino (NH2) functional groups covalently bonded to a surface of the BNNT. Aqueous and organic solutions of these modified BNNTs are disclosed, along with methods of producing the same. The modified BNNTs and their solutions can be used to coat substrates and to make nanocomposites.
