▎ 摘  要

NOVELTY - Method (100) for depositing nanocomposite onto electrode and enhancing performance in monitoring various parameters, involves stabilizing (110) a reduced graphene oxide (rGO) with a poly(sodium 4-styrenesulfonate) (PSS) to form a reduced graphene oxide-poly(sodium 4-styrenesulfonate) (rGO:PSS), preparing (120) a solution of rGO:PSS-PEDOT:PSS nanocomposite by mixing 50 mu l rGO:PSS with 50 mu l conductive polymer comprising sulfur and/or nitrogen and poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), centrifuging (130) the solution of rGO:PSS-PEDOT:PSS nanocomposite at 1500 rpm for 30 minutes, storing (140) the solution of rGO:PSS-PEDOT:PSS nanocomposite at 4 degrees C, electropolymerizing (150) 3 mu l rGO:PSS-PEDOT:PSS nanocomposite solution onto an electrode to fabricate a rGO:PSS-PEDOT:PSS/electrode, and drying (160) for 24 hours under a laminar flow hood. USE - Method useful for depositing nanocomposite and enhancing performance in monitoring various parameters in electronic and solar applications. ADVANTAGE - The method deposits solution of reduced graphene oxide-poly(sodium 4-styrenesulfonate)-poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) nanocomposite onto electrode in a certain way which can enhance the performance in monitoring various parameters e.g. sensitivity of detection, selectivity towards target analyte, effective surface area of electrode and low detection limit. The method is facile and affordable for resource-constrained settings.
