Abstract

original image

Hey ho, let's GO: Graphene oxide platelets can be self-assembled into highly ordered, mechanically flexible carbon films with tunable porous morphologies. Further nitrogen doping enhanced the electrical properties and supercapacitor performances of the carbon-based assemblies, and provided chemical functionalization.
