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.
