摘要
BN tubular micro-/nanostructures were prepared in large scale from a simple unique chemical process onto the surface of a graphite substrate, using polypropylene and boron oxide as solid sources, and under an ammonia flow. The as-grown product is featured by a unique hierarchical tubular structure with BN microtubes covered by BN multiwall nanotubes a few nanometers in diameters. Elegant BN flowers were grown on the same substrate when omitting carbon precursors. These BN micro-/nanotubes open new perspectives in (nano)composite materials with enhanced matrice-to-fibers bonding.
