摘要:
Graphitic platelets (wings) on carbon nanotubes are produced using a new two-step chemical vapor deposition method (see Figure and inside cover). Chemical attack during the process, aided by curvature-induced strain, rips open the outer nanotube walls and produces an irregular and corrugated surface. The new morphology, which presents a highly modulated and active nanotube surface, could facilitate posterior functionalization or direct composite fabrication.
