▎ 摘　　要

NOVELTY - A graphene-based conductive ink comprises 2-25 wt.% conductive component, 5-25 wt.% binding agent, 0.1-5 wt.% additive, 0.1-2 wt.% pH-adjusting agent and remainder of solvent. USE - Graphene-based conductive ink is used for forming flexible conductive film (claimed). ADVANTAGE - The conductive ink has high dispersibility, printing effect and conductive effect, and is economical. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene-based conductive ink, which involves dispersing the pH adjusting agent into the solvent, mixing obtained mixed liquid with the binding agent, and then adding conductive component and additive to mixture; and (2) flexible conductive film.
