Abstract

In present work, GO-hexamethylene tributylammonium iodide (GO-HMA-TBAI) was synthesized via chemical routes. The structural and valance state of the prepared samples was characterized by X-ray diffraction, X-ray photoelectron spectroscopy. For improving the electrochemical performance of conductive polymer, poly ortho aminophenol (POAP)/ GO-HMA-TBAI composite films have been fabricated by POAP electropolymerization in the presence of GO-HMA-TBAI as active electrodes for electrochemical supercapacitors. Different electrochemical methods including galvanostatic charge discharge experiments, cyclic voltammetry and electrochemical impedance spectroscopy have been applied to study the system performance. The supercapacity behavior of the composite film was attributed to the high active surface area, high conductivity of the composite film and synergism effect between conductive polymer and GO-HMA-TBAI.
