Polycrystalline graphene films grown by chemical vapor deposition (CVD) possess outstanding electrical and optical properties, which make them alternative materials for applications in transparent conductive films (TCF). However, the high density of topological defects such as line dislocations and grain boundaries (GB) adversely affect the electrical conductivity of graphene films. Here, we find that silver nanocomposites (NC) consisting of nanowires and nanoparticles, which assembled with graphene to form a hybrid film can drastically decrease the sheet resistance (Rs) to 26 kΩ sq−1 comparable to that of the theoretical Rs of intrinsic graphene. Our results indicate that the graphene-based hybrid film is an alternative candidate for realizing high-performance TCF.
