Low-aspect ratio graphite hollow nanostructures

Abstract

The synthesis of hollow nanostructures has attracted great attention in nanotechnology. As compared to the long hollow structures, the short counterparts could serve other compelling applications, and have become a hotspot in the field of nanomedicine. In the present work, a novel brand graphite-based nanostructure with a special cup-shaped feature was synthesized via the pyrolysis of a solid carbon source of polymethylmethacrylate (PMMA). These nanocups are typically characterized with open ends, tapered hollow cavities and slowly convergent roots, which are free standing on the graphene films with very low length/diameter aspect ratios as compared to conventional carbon nanotubes. The growth mechanism of these cups was proposed. It is promising that the present graphite nanocups could have potential applications in drug delivery.
