Abstract

The invention discloses a formula and preparation method of an ink for ink jet printing, which uses a nano cuprous oxide conductive ink as the main conductive component. The novel nano cuprous oxide conductive ink comprises 5-70 wt% of nano cuprous oxide, 5-70 wt% of colorant, 0-5 wt% of dispersant and 5-25 wt% of ink carrier solvent. The method comprises the following steps: proportionally and sequentially mixing the nano cuprous oxide, additives and ink carrier, carrying out ultrasonic dispersion, thoroughly mixing, and sintering. The conductive ink for ink jet printing has the characteristics of high feasibility, low cost, low resistance, adjustable viscosity and the like, and can be easily jetted.
