▎ 摘 要
NOVELTY - Preparation method of single crystal graphene conductive ink involves obtaining a predetermined amount of single crystal graphene, and preparing ink based on predetermined amount of single crystal graphene. USE - The method is useful for preparation of single crystal graphene conductive ink (claimed). ADVANTAGE - The method improves the conductivity of graphene conductive ink using single crystal graphene as conductive filler, reduces the strong scattering of electrons caused by grain boundary defects caused by the use of polycrystalline graphene, and solves the technical problem of low conductivity of the polycrystalline graphene conductive ink.
