▎ 摘　　要

NOVELTY - Preparing graphene ink involves dispersing graphite flakes in an organic solvent, ultrasonicating dispersion, separating the supernatant by centrifuging the ultrasonically treated dispersion to remove the supernatant followed by the addition of 1-5C alcohol to the supernatant. The resultant is filtered to remove the exfoliate adhered to the filter. USE - Method for preparing graphene ink (claimed). ADVANTAGE - The method enables to prepare graphene ink which has high dispersibility.
