We suggest facile method for improving significantly conductivity of reduced graphene oxide (RGO) film with a negligible loss of transmittance by introducing well dispersed low density AgNWs below the percolation threshold and optimal thermal annealing. This method provides high reduction ratio of sheet resistance of RGO film (~98%). The RGO-AgNW hybrid film after thermal annealing at 250 °C showed low sheet resistance on the order of 102 Ω/sq at a transmittance of 80%. This value is about two orders of magnitude lower than pristine RGO film with sheet resistance of 104 Ω/sq. This RGO-AgNW hybrid films show high ratio of DC to optical conductivity (σDCOP ~ 4.2). This successful strategy can be suspected as the most effective way to reduce the sheet resistance of RGO films for a variety of optoelectronic device applications.
