Abstract

The graphene oxide/silver nanoparticles (GO/AgNPs) composite films were prepared by spin coating combined with electrostatic self-assembly technology, and the reduced graphene oxide/silver nanoparticles (RGO/AgNPs) composite films were finally obtained at 600°C under Ar/H2 atmosphere for 2 h. With the increase of the number of film layers, the absorption characteristic peak intensity of reduced graphene oxide (RGO) also gradually increases, indicating that the composite film grew uniformly. The conductivity of graphene/silver nanoparticles composite films not only increased with the decreased of particle size, but also increased with the increased of self-assembly and spin-coating times. The lowest sheet resistance of RGO/AgNPs28-10 film was only 0.392 kΩ/sq, which showed excellent conductive performance.
