Abstract

This disclosure relates to graphene-based conductive ink compositions and methods thereof. The compositions exhibit improved bonding to a substrate, excellent resistance to hydrolysis, and improved mechanical strength and electrical conductivity. This disclosure relates to conductive ink compositions and methods for obtaining the conductive ink, the conductive ink comprising 4 to 25% by weight of graphene as a first carbon-based conductive material, 0.1 to 10% by weight of a second carbon-based conductive material, 0.01 to 5% by weight of a first dispersant comprising styrene-coacrylate for improved dispersibility, 0.01 to 3% by weight of a second dispersant for preventing aggregation, 0.1 to 60% by weight of a binder comprising polyimide, and 0.1 to 90% by weight of a solvent.
