    • Abstract


      Graphene-based materials such as graphene oxide (GO) and chemically reduced graphene oxide (rGO) thin films have been fabricated using electrostatic spray deposition (ESD), followed by thermal annealing under Ar/H$_2$ atmosphere. The thickness and surface morphology of thin films of GO and rGO on silicon substrates were controlled by varying deposition time and content of GO/rGO in tetrahydrofuran (THF) solution. Here, we present a comparative analysis between GO and rGO thin films. Water contact angle (WCA) measurements of these thin films were ${\sim}$88$^{\circ}$for the GO films and >127$^{\circ}$for the rGO films. We discuss how their hydrophobic behaviour is influenced by removal of oxygencontaining functional groups during the reduction process.
