(cu rr ently amended) A method for preparing graphene ribbons, comprising: (a) preparing a graphitic materia l, where 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)er-felewed-by, 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 lay ers that are translated by a half hexagon relative to an AA stacked structure.
The method of claim 1, wherein the graphitic material has an aspect ratio more than 10 [[,]] and h a s an outer diameter of 2- n 2 to 300 nm, and the pr oduct graphene ribbons of step (b) have a width equal to the outer diameter of the graphitic material or less than 1/2 of the outer diameter of the graphitic material.
The method of claim 1, wherein the graphitic material is a tube shape or a fibrous shape.
The method of claim 1, step (b) further eempPiag- comprises a sonication process to scatter the p r eeesse d product graphene ribbons.
