Reactive silver inks for printing highly conductive features (>10⁴ S/cm) at room temperature have been created. These inks are stable, particle-free, and suitable for a wide range of patterning techniques. Upon annealing at 90 °C, the printed electrodes exhibit an electrical conductivity equivalent to that of bulk silver.
