Description

technical field [0001] The invention belongs to the field of conductive inks, in particular to a graphene conductive ink and a preparation method thereof. Background technique [0002] Conductive ink is a functional ink, usually composed of point-to-point functional materials and matrix materials. Among them, the conductive functional material realizes the conductive function by being dispersed in the ink carrier. Most of the existing conductive functional materials are conductive metal powder and conductive carbon material; the matrix material usually acts as a binder and a seasoning component to adjust the viscosity of the ink or Improve the mechanical support of the ink. At present, there are practical conductive inks on the market, including gold-based conductive inks, silver-based conductive inks, copper-based conductive inks, carbon-based conductive inks, etc., which are widely used in printed circuits, electrodes, electroplating layers and other fields. However, con...
