Graphene is a monolayer of carbon atoms that are tightly packed into a two-dimensional, honeycomb crystal structure. This extremely thin nanomaterial has shown fascinating properties and holds the promise for future carbon-based device architectures owing to characteristics such as high mechanical stiffness, extraordinary electronic transport properties and excellent antibacterial activity. Silver nanoparticles with high electric conductivity were deposited onto the graphene sheets with good dispersity and conductivity could be maintained. In this work, Ag nanoparticles with controlled sizes were deposited on graphene oxide sheets by microwave reduction method, and we prepared thin films containing Ag-graphene oxide using a vaccum filtration method. Ag-graphene oxide thin films was reduced by HI-AcOH. The successful synthesis of the Ag-reduced graphene thin films was confirmed by SEM, TEM, EDS, XRD and resistivity was determined by four-point probe. |
