▎ 摘　　要

NOVELTY - An ink preparation involves preparing photosensitive copolymer; dispersing graphene oxide in N,N-dimethyl formamide, adding hydrazine hydrate, reacting, cooling, adding photosensitive copolymer, dispersing in common solvent, cooling, centrifuging, washing and drying to get photosensitive graphene; and mixing photosensitive prepolymer, photoinitiator, reactive diluent and photosensitive graphene and stirring. USE - Method for preparing ink (claimed) used for electronic information products such as touch screen, radio-frequency identification and flexible circuits. ADVANTAGE - The ink has good thermal conductivity properties, low resistivity electronic circuit, large adhesion and high hardness. DETAILED DESCRIPTION - An ink preparation comprises dissolving glycidyl methacrylate, vinylcarbazole, azobisisobutyronitrile and solvent with stirring through nitrogen for 25-30 minutes, sealing, reacting at 50-100 degrees C for 8-16 hours, cooling to room temperature, adding acrylic acid or methacrylic acid, triphenylphosphine as catalyst and hydroquinone or resorcinol as polymerization inhibitor, reacting at 85-120 degrees C for 8-16 hours, precipitating and vacuum drying in oven at 20-80 degrees C to get photosensitive copolymer; dispersing graphene oxide in N,N-dimethyl formamide, adding hydrazine hydrate, reacting at 70-100 degrees C for 8-12 hours, cooling, adding photosensitive copolymer, dispersing in common solvent, cooling, centrifuging, washing and drying to get photosensitive graphene; and mixing 50-80 wt.% photosensitive prepolymer, 3-6 wt.% photoinitiator, 6-15 wt.% reactive diluent and 3.5-15 wt.% photosensitive graphene and stirring at room temperature.
