Abstract
The [Cu(btec)0.5DMF] (H4btec=1,2,4,5-benzenetetracarboxylate acid) was electrosynthesized on the graphite working electrode by applying catholic potential. The [Cu(btec)0.5DMF] grows on a graphite surface which results from the coordination of 1,2,4,5-benzenetetracarboxylate anions with Cu2+ cations. The electrosynthesized [Cu(btec)0.5DMF] was characterized by X-ray diffraction, scanning electron microscopy. Furthermore, POAP/Cu(btec)0.5DMF nanocomposite film electrosynthesized on the surface of the carbon paste electrode by cyclic voltammetry. Different electrochemical methods including galvanostatic charge–discharge experiments, cyclic voltammetry and electrochemical impedance spectroscopy are carried out in order to investigate the performance of the system. This work introduces new nanocomposite materials for electrochemical redox capacitors with advantages including ease synthesis, high active surface area and stability in an aqueous electrolyte.
Highlights
Polyaniline (PANI) is one of the most important conducting polymers because of its unique electrical, optical, and optoelectrical properties, as well as its ease of preparation and its excellent environment stability
The variety of results for conductivity of the Poly ortho aminophenol (POAP) film reported in the literature [1,2,3] show that the electrochemical response of POAP is strongly influenced by the experimental procedure used to produce the polymer film, dopant anions and the purity starting monomer [1,2,3,4]
Some differences were observed between experimental and simulated patterns. Such differences in intensities in Metal-organic frameworks (MOFs) are common [19, 20] since the structure is modeled in the absence of guests in the pores, while the simulated pattern is obtained in the presence of the solvent, having guests in the pores, which affects the peak intensities and positions
Summary
Polyaniline (PANI) is one of the most important conducting polymers because of its unique electrical, optical, and optoelectrical properties, as well as its ease of preparation and its excellent environment stability. Ortho aminophenol (POAP) gives a surface film of interesting electrochemical and electrochromic properties when it is electropolymerised in acidic solution. This film is electroactive in aqueous and nonaqueous solutions containing protons but no response is observed at pH-value higher than pH 7. The insertion of nanoscale fillers may improve the electrical and dielectric properties of host conductive polymer materials. For the first time to the best of our knowledge, we electrosynthesized [Cu(btec)0.5DMF] (Fig. 1) on the surface of graphite electrodes by applying a constant voltage to the solution of H4btec, metal ions and NaNO3. The capacitive behavior of nanocomposite was tested by cyclic voltammetry, galvanostatic charge discharge and impedance spectroscopy techniques
