GRAPHENE BASED HYBRID THIN FILMS AND THEIR APPLICATIONS

摘要

Graphene-based hybrid films are made by coating electrically conductive nanostructures (such as carbon nanotubes or conductive nanowires) onto a metal substrate, and growing a graphene layer between the nanostructures and the substrate. The nanostructure coating on the substrate yields nucleation sites for the growth of the graphene layer. The process provides hybrid films in which graphene domains are electrically connected by the nanotubes or nanowires. Integral bonds (e.g., chemical bonds) are produced between the nanostructures and the graphene to provide improved electrical conductivity, via contact in excess of van der Waals forces.
