▎ 摘　　要

NOVELTY - Preparing a ink-jet printing graphene-doped nano-silver conductive ink comprises (i)1 preparing graphene-containing silver solution system, adjusting the pH value of the silver solution containing graphene and dispersant, controlling the reaction temperature under ultrasonic stirring and dropping a reducing agent to reduce nano-silver particles and washing, and (ii) adjusting the viscosity, surface tension and solid content. USE - The method is useful for preparing a ink-jet printing graphene-doped nano-silver conductive ink. ADVANTAGE - The method: is simple, fast and suitable for industrial large-scale.
