NOVELTY - A conductive ink comprises graphene composite, which is prepared by mixing graphite with graphene stripper and separating using ultrasonic water phase. The graphene stripper comprises 2,9-bis-aminomethyl-anthra(2,1,9-6,5,10)diisoquinoline-1,3,8,10-tetraone compound (I). USE - Conductive ink. ADVANTAGE - The ink has excellent conductivity. DETAILED DESCRIPTION - A conductive ink comprises graphene composite, which is prepared by mixing graphite with graphene stripper and separating using ultrasonic water phase. The graphene stripper comprises 2,9-bis-aminomethyl-anthra(2,1,9-6,5,10)diisoquinoline-1,3,8,10-tetraone compound of formula (I). R1-R4 = H, CH3, C2H5, C3H7 or C4H9;and n = 2-5. An INDEPENDENT CLAIM is included for preparation of conductive ink, which involves mixing graphene composite with remaining raw materials, ultrasonically shaking and dispersing.
