▎ 摘 要
We report on the synthesis of graphene nanodiscs by electrochemical assisted micromechanical exfoliation of graphite sheet. High resolution electron micrographs show unique circular disc like polycrystalline graphene structures. The nanodiscs are transparent, range between 20-50 nm in diameter, consists 1-2 layers, do not fold, easily dispersed in aqueous ethanolic solution and exhibit supramolecular behavior of self assembly. The nanodiscs exhibit dual characteristics, viz., circular disc like structures when dispersed in aqueous ethanolic solution, and flake like structures when dehydrated. The article addresses in detail the intricate intrigues of the synthesis, characterization and its supramolecular behavior.
