▎ 摘　　要

NOVELTY - An easily machinable graphene oxide slurry is prepared by oxidizing graphite to prepare graphite oxide, stripping, dispersing in solvent, and concentrating to 30-150 mg/mL. USE - Method for preparing easily machinable graphene oxide slurry used for 3D printing (claimed). ADVANTAGE - The method is simple. The system has excellent performance, avoids graphene agglomeration, and suitable for complicated 3D structures for fields of separation, adsorption, bio-medical, sensing, energy storage and heat conduction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide 3D system comprising 3D printing, manual kneading and molding.
