NOVELTY - Preparing a graphene/silver composite ink comprises adding graphene into silver nitrate solution, uniformly mixing, performing chemical reduction reaction in the presence of a resin system and a solvent system to obtain a silver nitrate/graphene spherical composite powder, ball milling the silver nitrate/graphene spherical composite powder using a planetary ball mill to obtain a graphene/silver spherical powder, dispersing the graphene/silver spherical powder using a high speed disperser, grinding the powder, and stirring. USE - The method is useful for preparing a graphene/silver composite ink (claimed), which is useful in electronic information products such as touch screens, a radio-frequency identification device, a flexible circuit, and a super capacitor. ADVANTAGE - The method prepares the graphene/silver composite ink with improved electric conductivity, high fineness and hardness, good adhesive force, and reduced electronic circuit resistance.
