▎ 摘　　要

NOVELTY - Preparing graphene conductive ink comprises adding 5-30 pts. wt. graphene powder into 50-100 pts. wt. polar solvent, and ultrasonically dispersing to obtain a graphene dispersion, uniformly mixing and stirring 20-80 pts. wt. heat-resistant phenolic epoxy polyurethane resin and 5-20 pts. wt. acrylic resin to obtain the resin mixture and adding graphene dispersion into the resin mixture under stirring. USE - The graphene conductive ink is useful in heating element (claimed), preferably preparing three-dimensional curved heating element. ADVANTAGE - The method enables the graphene to be uniformly dispersed in the ink system, the conductive layer has a uniform square resistance, and the surface temperature of the heating element is uniform. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene conductive ink comprises 5-30 pts. wt., preferably 10-18 pts. wt. graphene powder, 50-100 pts. wt., preferably 60-85 pts. wt. polar solvent, 20-80 pts. wt., preferably 50-75 pts. wt. heat-resistant phenolic epoxy polyurethane resin and 5-20 pts. wt., preferably 15-18 pts. wt. acrylic resin.
