The aim of this work is to fabricate supercapacitor electrode based on poly (3-hexyl-thiophene-2, 5-diyl) (P3HT) and single-walled carbon nanotubes (SWCNTs) nanocomposites with different ratios onto a graphite sheet as a substrate with a wide voltage window in nonaqueous electrolyte. Structural, morphological and electrochemical properties of the prepared nanocomposites of P3HT/SWCNTs were studied and discussed. The electrochemical properties included cyclic voltammetry (CV), galvanostatic charging-discharging (GCD), and electrochemical impedance spectroscopy (EIS) were investigated. The obtained results indicated that P3HT/SWCNTs nanocomposite possesses higher specific capacitance than that present in its individual component. The high electrochemical performance of the nanocomposite was due to formation of microporous structure which facilitates ions diffusion and electrolyte penetration in these pores. The morphological micrographs of the purified SWCNTs had buckypaper structure while the photomicrographs of P3HT/SWCNTs showed that SWCNTs appear behind and front of the P3HT nanospheres. The specific capacitance of 50% SWCNTs at 0.5 Ag−1 was found to be 245.8 Fg−1 compared with that of pure P3HT of 160.5 Fg−1.

“…Polythiophene (PT) and its derivatives are very promising conducting polymers due to their numerous remarkable properties such as environmental and thermal stability [1][2][3], high electrical conductivity [4][5][6] and interesting electronic and optical characteristics [7][8][9][10]. Thanks to these features, polythiophene offers several industrial applications in various fields, including electronic devices such as transistors [11][12][13], organic light-emitting diodes (OLEDs) [14,15], photovoltaic cells [16][17][18][19], electrochromic devices [20,21] and sensors [22][23][24].…”

Electropolymerization of thiophene was performed in aqueous acidic media on various substrates, namely, titanium, nickel and SS steel. The films were successfully elaborated using voltamperometric, chronopotentiometric and chronoamperometric techniques. It was shown that concentrated acids increase the solubility of the monomer, lower its oxidation potential and inhibit the dissolution of the working electrode. Furthermore, the electrosynthesized polythiophene (PT) films are homogeneous and present similar properties to those obtained in organic media. On the other hand, analyses by X-ray photoelectron and infrared spectroscopies indicate the higher oxidation state of the polymers and the contribution of the supporting electrolyte in the doping process. In addition, IR spectra have demonstrated the strictly a, a’ linked polythiophene chains and an estimated degree of polymerization (DP) of about 40. Finally, scanning electron microscopy (SEM) has been used to characterize the morphology of the obtained coating. In this context, the nature of the films depends closely on the type of the electrode, the electrosynthesized mode and the electrolytic medium.
