▎ 摘 要
NOVELTY - A three-dimensional nanostructure is obtained by laminating nano-material on graphene film. The nano-material is chosen from nanowires, nanotubes, nanorods, nanoneedles and nanoparticles. USE - Three-dimensional nanostructure is used for field-emitting device. ADVANTAGE - The three-dimensional nanostructure has excellent flexibility and elasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of three-dimensional nanostructure.
