Abstract:
1. A method for preparing graphene ribbons, comprising: (a) preparing a graphitic material, wherein the graphitic material is composed of stacked graphene helices, wherein each of the stacked graphene helices is grown along its long axis; and (b) (1) shortening the graphitic material by applying an energy, and (2) simultaneously with or subsequent to step (1), decomposing the shortened graphitic material into product graphene ribbons, wherein the graphitic material of step (a) has a turbostratic stacked structure or an AA′ stacked structure, wherein the AA′ stacked structure is a graphitic structure comprising alternate graphene layers that are translated by a half hexagon relative to an AA stacked structure.
