▎ 摘　　要

NOVELTY - An antioxidant copper-graphene composite conductive ink comprises 30-70 parts mass conductive filler, 3-20 parts mass binder, 1-5 parts mass additive and 25-65 parts mass solvent. The conductive filler comprises formate-modified copper material and/or conductive carbon material in a mass ratio of (3-12):1. USE - Antioxidant copper-graphene composite conductive ink (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of antioxidant copper-graphene composite conductive ink, which involves (i) preparing formate-modified copper material, (ii) dissolving binder material in ink solvent, mixing and stirring to obtain transparent binder mixture, (iii) adding copper material and conductive filler into a ball mill for ball milling for 0.1-10 hours, then adding binder mixture and additive into a ball mill and ball milling for 0.5-50 hours at a speed of 150-550 rpm to obtain slurry, (iv) filtering the slurry, and obtaining antioxidant copper-graphene composite conductive ink.
