Reduced graphene oxide (rGO), is a versatile material used in a variety of next generation electronics, micro-supercapacitors, and flexible sensors. rGO is developed as a cost efficient alternative to graphene of similar quality. rGO has favorable properties of high conductivity, and surface area, constituting promising energy storage, and sensing capabilities comparable to other carbon materials. The desired properties of rGO allow for the development of flexible rGO/Au electrodes for polychlorinated biphenyls (PCB) and isopropyl alcohol (IPA) sensing upon appling gold nanosheets. This is achieved via variation in the operational laser settings (Fusion Pro Epilog Engraver) including frequency, and intensity, in addition to the varied flexible substrate (silicone, neoprene rubber). A scanning electron microscope (SEM) is used to confirm the reduction process of GO and characterize the structural changes with varying parameters. Additionally, impedance and cyclic voltammetry (CV) tests are conducted to estimate the electrical and electrochemical performance of the fabricated sensor, and their change when exposed to various chemical vapors. The flexible micro-supercapacitor sensor shows sensible results throughout the fabrication and testing processes.
