摘要： The present invention provides methods of forming graphene films on various non-catalyst surfaces by applying a carbon source and a catalyst to the surface and initiating graphene film formation. In some embodiments, graphene film formation may be initiated by induction heating. In some embodiments, the carbon source is applied to the non-catalyst surface before the catalyst is applied to the surface. In other embodiments, the catalyst is applied to the non-catalyst surface before the carbon source is applied to the surface. In further embodiments, the catalyst and the carbon source are applied to the non-catalyst surface at the same time. Further embodiments of the present invention may also include a step of separating the catalyst from the formed graphene film, such as by acid etching.
