NOVELTY - Printing cured graphene-based conductive ink comprises (i) mixing 10-30 pts. wt. graphene, 10-20 pts. wt. chlorinated polypropylene resin, 20-60 pts. wt. solvent, 8-20 pts. wt. graphene quantum dot, 20-70 pts. wt. monomer, 1-5 pts. wt. crosslinking agent and 1-10 pts. wt. auxiliary agent, performing ultrasonic dispersion, then transferring dispersion to grinder and then grinding until the ink fineness is less than 10 mu m to obtain graphene conductive ink, and (ii) adding initiator into graphene conductive ink obtained in step (i), where addition amount is 0.1-1 wt.% of the monomer, then spraying on the surface of substrate based on the design pattern and then performing process at 80-150 degrees C under atmosphere. USE - The method is useful for printing cured graphene-based conductive ink.
