Graphene oxide recycling process

A process for graphene oxide reclamation and recycling, said process comprising:

• a) contacting graphene oxide with a nonpolar hydrocarbon solvent;
• b) washing said graphene oxide in a solvent selected from the group consisting of acetone, 2-butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone and mixtures thereof a first time;
• c) washing said graphene oxide in a solvent selected from the group consisting of acetone, 2-butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone and mixtures thereof a second time;
• d) drying said graphene oxide by contacting said graphene oxide with a nitrogen stream;
• e) washing said graphene oxide in a solvent selected from the group consisting of ethanol, methanol, isopropyl alcohol, propanol, butanol and mixtures thereof a first time;
• f) washing said graphene oxide in a solvent selected from the group consisting of ethanol, methanol, isopropyl alcohol, propanol, butanol and mixtures thereof a second time;
• g) washing said graphene oxide in a solvent selected from the group consisting of acetone, 2-butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone and mixtures thereof a third time;
• h) washing said graphene oxide in a solvent selected from the group consisting of acetone, 2-butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone and mixtures thereof a fourth time;
• i) sonicating said graphene oxide in water;
• j) permitting said graphene oxide to settle out of said water and collecting said settled graphene oxide;
• k) washing said graphene oxide with water;
• l) washing said graphene oxide in a solvent selected from the group consisting of acetone, 2-butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone and mixtures thereof a fifth time;
• m) washing said graphene oxide in a solvent selected from the group consisting of acetone, 2-butanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone and mixtures thereof a sixth time;
• and
• n) actively and/or passively drying said graphene oxide.
