PURPOSE: A conductive ink is provided to be inexpensive, has a polymer bead which has an excellent compatibility weight while being superior with the binder and solvent thereby making it an excellent electric conductance. CONSTITUTION: A polymer bead for a conductive ink comprises a nano graphene on the surface thereof. The nano graphene sheet comprises a graphite, sulfuric acid(H2SO4), potassium permanganate(kMnO4), hydrogen peroxide(H2O2), and ammonia and hydrazine. The conductive ink comprises the polymer bead and additionally comprises a binder resin, solvent and additive. The binder resin contains one or more selection from an acryl-based binder resin and a polyester-based binder resin. |
