Abstract
The present application relates to boron nitride nanotube (BNNT)-nanoparticle composites, to methods of preparing such composites and their use, for example, in metal/ceramic matrix composites and/or macroscopic assemblies. For example, the methods comprise subjecting a source of hydrogen, a source of boron, a source of nitrogen and a nanoparticle precursor to a stable induction thermal plasma and cooling the reaction mixture to obtain the composite.
Claims16
A method for preparing a boron nitride nanotube (BNNT)-nanoparticle composite, the method comprising:
- subjecting a source of hydrogen, a source of boron, a source of nitrogen and a nanoparticle precursor that is a non-catalytic metal or a non-catalytic ceramic to a stable induction thermal plasma to form a reaction mixture in the plasma;
- and
- cooling the reaction mixture to obtain the BNNT-nanoparticle composite with nanoparticles attached to on outer surface of BNNTs.
