A method for preparing a conductive adhesive and a conductive adhesive. The preparation method comprises the following steps: step 1, a graphene oxide is prepared; step 2, a functional reagent is provided and reacts with the graphene oxide to prepare a functional graphene; step 3, a curing agent and an organic solvent are provided, mixed with a certain amount of conductive particles and then subjected to an ultrasonic treatment to prepare a conductive particle dispersion, the conductive particle being the functional graphene or a mixture of the functional graphene and other conductive particles; step 4, an adhesive resin is provided, and the adhesive resin is diluted using the organic solvent in step 3; and step 5, the adhesive resin diluted in step 4 is mixed with the conductive particle dispersion to prepare a conductive adhesive pre-mixture, the conductive adhesive pre-mixture is stirred repeatedly until uniform and further dispersed using ultrasound, and then the organic solvent is removed to prepare the conductive adhesive. |
