Abstract:
1. A dispersible and electrically conductive nano graphene platelet (NGP) material comprising at least a single-layer or multiple-layer graphene sheet, wherein said NGP material has an oxygen content no greater than 25% by weight and no less than 5% by weight, wherein said nano graphene platelet material is obtained from a process comprising: (a) preparing a pristine NGP material from a graphitic material; and (b) subjecting said pristine NGP material to an oxidation treatment to obtain said dispersible and conductive NGP material and wherein said graphitic material is selected from the group consisting of natural graphite, artificial graphite, graphite oxide, graphite fluoride, graphite fiber, carbon fiber, carbon nano-fiber, carbon nano-tube, mesophase carbon micro-bead (MCMB) or carbonaceous micro-sphere (CMS), soft carbon, hard carbon, and combinations thereof.
