Facile method for the environmentally friendly fabrication of reduced graphene oxide films assisted by a metal substrate and saline solution

In this study, a graphene oxide film supported on a steel sheet was prepared by electrophoretic deposition and then treated with a NaCl solution to form a reduced graphene oxide (rGO) film. The rGO film displayed an electrical conductivity of 40.7 S m?1, and was prepared using benign and environmentally friendly reduction conditions
