The organization of carbon materials, especially planar and mechanically flexible graphene, into complex three-dimensional geometries is a major challenge for their ultimate utilization in various applications. Herein, we report a facile and controllable approach for preparing macroporous and highly ordered three-dimensional assemblies of chemically modified graphene using the so-called ‘Breath Figure’ method. Polymer-grafted graphene oxide was assembled into macroporous films by self-organized aqueous droplets. Subsequent pyrolysis yielded mechanically flexible carbon films that exhibited highly ordered morphologies. Incorporation of a nitrogen-doping process into the aforementioned protocol enhanced the electrical properties and supercapacitor performances of the carbon-based assemblies, and provided chemical functionality for further chemical derivitization. |
