▎ 摘 要
NOVELTY - Preparation of graphene ink involves growing graphene on a metal substrate, removing the metal substrate, and dispersing the graphene in a dispersion medium. USE - Preparation of graphene ink (claimed). ADVANTAGE - The method enables efficient preparation of graphene ink with high quality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene ink, which comprises the dispersion medium, and a graphene dispersed material dispersed in the dispersion medium.
