NOVELTY - Conductive ink comprises 100 pts. wt. deionized water, 1-10 pts. wt. polyaniline-polyvinyl alcohol (PANI-PVA), and 20-70 pts. wt. graphene. USE - The conductive ink is useful in technical field of printing ink. ADVANTAGE - The coating: is aqueous; has improved stability and enhanced electrical conductivity and adhesion. The method is simple, convenient and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing conductive ink, comprising (i) adding PANI-PVA into deionized water for ultrasonic dispersion to obtain uniform PANI-PVA aqueous dispersion, and (ii) adding graphene to PANI-PVA aqueous dispersion, and placing material comprising graphene and PANI-PVA aqueous dispersion in dispersing machine to obtain aqueous graphene conductive ink by high-speed shear dispersion, where the stirring speed is 1000-10000 revolutions/minutes, and the stirring time is 1-24 hours in the disperser.
