Figure 1: Fabrication of CGFs.
From: Development of an ultra-thin film comprised of a graphene membrane and carbon nanotube vein support
(a) Cu foil with graphene (Gr) on both sides after CVD growth. (b) Cu foil with only one side of graphene after oxygen RIE. (c) Graphene/Cu foil cross-stacked by CNT networks, and then infiltrated by alcohol. (d) CGF with a highly ordered layer-to-layer graphene/CNT network stacking structure, after etching the Cu foil with FeCl3/HCl solution.
