| titleOfInvention | Environmentally benign production of graphene oxide |
| abstract | A method of producing isolated graphene oxide sheets directly from a graphitic material, comprising: a) mixing multiple particles of a graphitic material, an optional oxidizing liquid, and multiple particles of a solid carrier material to form a mixture in an impacting chamber of an energy impacting apparatus; b) operating the energy impacting apparatus with a frequency and an intensity for a length of time sufficient for peeling off graphene sheets from the graphitic material and transferring the graphene sheets to surfaces of the solid carrier material particles to produce graphene-coated solid carrier particles inside the impacting chamber; and c) sequentially or concurrently oxidizing and separating the graphene sheets from the solid carrier material particle surfaces to produce isolated graphene oxide sheets. The process is fast (1-4 hours as opposed to 5-120 hours of conventional processes), has low or no water usage, environmentally benign, cost effective, and highly scalable. |
