Fabrication and Surface Deformation of Boron Nitride Nanotubes by RF Plasma and Ion Beam

Boron Nitride Nanotubes (BNNT) are one of the candidate materials for storing hydrogen by physical adsorption. It has been reported that this storage capacity increases as crystallinity nanostructures decreases. Here, BNNT was synthesized using an RF plasma torch system, and surface irradiated with nitrogen ions ion beam device, changes in microstructure were subsequently investigated. A multi-walled a wall thickness about 5 nm 60 kW torch. Amorphous impurities generated during synthesis process removed heat treatment membrane filtering. Then 40 minutes at energies keV 50 keV, respectively, irradiation device. The following confirmed HR-TEM, Raman spectrometer FT-IR spectrometer. tube walls disordered irradiation. At located middle became disordered, which attributed to increase penetration depth due higher energy. maximum peak spectra also shifted lower frequency. Ion reduced nanostructures. potential improvement confirmed.
