The unique electrical and thermal properties of graphene has triggered numerous applications in optics, electronics, sensors and solar energy. These properties have resulted in devices that cater to water filtration, aerospace components, flexible electronics and photovoltaic cells. However the application of graphene for heat transfer enhancement is still relatively unexplored. In the recent years, graphene based coating materials as a result various graphene manufacturing techniques has gained a lot of attention. In this paper, we present a) detailed characterization of electrochemically generated solution consisting of graphene oxide (GO) and graphene and, b) dip coating of GO and graphene solution on copper substrate at various durations, and correlating the dip coat times with resultant surface morphology c) heat transfer performance of dip coated samples. The graphene oxide (GO) and graphene solution was characterized using dynamic light scattering and Fourier Transform Infrared (FTIR), and thermogravimetric analysis (TGA). The graphene oxide (GO) and graphene solution dip-coated copper surfaces were using X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and X-ray spectroscopy (EDS).
