▎ 摘  要

NOVELTY - Preparing graphene additive, comprises (i) dispersing graphene oxide in deionized water, ultrasonically oscillating at room temperature for 3-5 hours to obtain oxidized graphene dispersion solution having a concentration of 2-8 wt.%, (ii) adding polyaniline into the oxidized graphene dispersion solution obtained in step (i), stirring for 3-6 hours and uniformly dispersing to obtain mixed solution, and (iii) adding acetylene black, sodium carboxymethyl cellulose, hydroxyethyl cellulose, polyvinyl alcohol, sodium dodecylbenzenesulfonate into the mixed solution obtained in step (ii), and then stirring to obtain graphene additive. USE - The graphene additive is useful for electrically conductive ink (claimed). ADVANTAGE - The additive: has excellent dispersion stability and compatibility; and imparts excellent electrical conductivity and bonding properties to ink. The method: has simple process; and is environmentally friendly.
