▎ 摘　　要

NOVELTY - Preparing high-concentration graphene/black phosphorene dual-media aqueous dispersion, comprises preparing a graphene water dispersant including the first dispersant and the second dispersant, adding the ground black phosphorene powder into N,N-dimethylacryl urea for ultrasonic treatment in an ice-water bath, taking the precipitated and dried black phosphorene nanosheets, adding the black phosphorene nanosheets into the ethanol solution, and ultrasonically dispersing into aqueous solution by hydroxylation treatment to obtain black phosphorene aqueous dispersion, taking the graphene microchip, dividing into two parts, adding the first dispersant and the second dispersant respectively, ultrasonically dispersing the two parts respectively to obtain an aqueous dispersion of graphene microsheets, slowly dropping black phosphorene dispersion into the stirred first graphene aqueous dispersion, and carrying out refinement twice. USE - The high-concentration graphene/black phosphorene dual-media aqueous dispersion is useful in preparing dual-media conductive black shadow solution (claimed). ADVANTAGE - The method has low cost, simple technique, and is suitable for large-scale industrial production. The graphene/phosphorene aqueous dispersion has high temperature resistance, high through hole efficiency and so characteristics, and provides graphene layer with equivalent conductivity, toughness and adhesive force, which can be applied to printing circuit board the surface of multiple non-conductive substrate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for high-concentration graphene/black phosphorene dual-media aqueous dispersion.
