In this work, a novel method for electrode modification based on inkjet-printing of electrochemically synthesized graphene-PEDOT:PSS (GP-PEDOT:PSS) nanocomposite is reported for the first time. GP-PEDOT:PSS dispersed solution is prepared for use as an ink by one-step electrolytic exfoliation from a graphite electrode. GPPEDOT: PSS layers are then printed on screen printed carbon electrodes (SPCEs) by a commercial inkjet material printer and their electrochemical behaviors are characterized towards three most common electroactive analytes including hydrogen peroxide...
