NOVELTY - Configuration of graphene conductive ink comprises (i) mixing deionized water, absolute ethanol, and glycerol in a certain volume ratio; (ii) adding silver powder and graphene alcohol slurry to the mixed solvent in sequence, stirring with a glass rod, and performing ultrasonic dispersion; (iii) ultrasonically dispersing, adding aqueous polyurethane resin, aqueous acrylic acid emulsion using glass rod to stir and ultrasonically dispersing to obtain ink; (iv) utilizing ink pH meter to measure the ink pH, and using the viscometer to measure the ink viscosity; and (v) utilizing the JD200 Proo 3D printer to print the circuit board on the photo paper, and drying it at a certain temperature for a period of time and measuring the resistance. USE - The configuration of graphene conductive ink is useful for 3-D printing on paper. ADVANTAGE - The method is, environment-friendly, recycled and applied to three-dimensional printing of circuit board on photo paper.
