Poly (3‐methylthiophene) (P3MT) was modified by nickel oxide (NiO) and nickel sulfide (NiS) nanoparticles to enhance its electrochemical performance. The surface influence, crystalline structure, and electrochemical performance of the P3MT/NiO/NiS material were characterized and compared with that of pristine P3MT. It is found that surface modification can improve the structural stability of P3MT without decreasing its available specific capacitance. The electrochemical properties of synthesized P3MT/NiO/NiS electrode were evaluated using cyclic voltammetry and alternating current impedance techniques in 3 M KOH electrolyte. Specific capacitances of 253, 764, 932, and 1434 F g−1 were obtained for P3MT, P3MT/NiO, P3MT/NiS, and P3MT/NiO/NiS, respectively at 5 A g−1. This improvement is attributed to the synergistic effect of Ni2+ ions in the P3MT/NiO/NiS electrode material. The P3MT/NiO/NiS electrode in KOH has average specific energy and specific power densities of 1032 Wh kg−1 and 6192 W/kg, respectively. Only 2% of the capacitance's initial value is lost after 10,000 cycles. The resulting P3MT/NiO/NiS nanocomposite had very stable and porous layered structures. This work demonstrates that P3MT/NiO/NiS nanomaterials exhibit good structural stability and electrochemical performance, and are good material for supercapacitor applications.Highlights The P3MT/NiO/NiS nanocomposite is fabricated and characterized as supercapacitor electrode. The incorporation of NiO/NiS in the poly (3‐methylthiophene) has improved the electrochemical performance. The P3MT/NiO/NiS electrodes retained 98% of their specific capacitance after 10,000 cycles. The P3MT/NiO/NiS nanocomposite electrode showed specific capacitance of 1434 F g−1 at 5 A g−1. The stability of the nanocomposite was enhanced without altering its morphology and chemical structure.

Graphene oxide can be referred to as oxidized graphene. Similar to graphene, oxidized graphene possesses remarkable structural features, advantageous properties, and technical applications. Among polymeric matrices, conducting polymers have been categorized for p conjugated backbone and semiconducting features. In this context, doping, or nano-additive inclusion, has been found to enhance the electrical conduction features of conjugated polymers. Like other carbon nanostructures (fullerene, carbon nanotube, etc.), graphene has been used to reinforce the conjugated matrices. Graphene can be further modified into several derived forms, including graphene oxide, reduced graphene oxide, and functionalized graphene. Among these, graphene oxide has been identified as an important graphene derivative and nanofiller for conducting matrices. This overview covers essential aspects and progressions in the sector of conjugated polymers and graphene oxide derived nanomaterials. Since the importance of graphene oxide derived nanocomposites, this overview has been developed aiming at conductive polymer/graphene oxide nanocomposites. The novelty of this article relies on the originality and design of the outline, the review framework, and recent literature gathering compared with previous literature reviews. To the best of our knowledge, such an all-inclusive overview of conducting polymer/graphene oxide focusing on fundamentals and essential technical developments has not been seen in the literature before. Due to advantageous structural, morphological, conducting, and other specific properties, conductive polymer/graphene oxide nanomaterials have been applied for a range of technical applications such as supercapacitors, photovoltaics, corrosion resistance, etc. Future research on these high-performance nanocomposites may overcome the design and performance-related challenges facing industrial utilization.

A novel ternary polycarbazole/cadmium sulfide/hematite iron (III) oxide (PCz/CdS/α‐Fe2O3) nanocomposite was synthesized through in situ chemical polymerization method. The phase structure and morphology of PCz, PCz/CdS, PCz/α‐Fe2O3, and PCz/CdS/α‐Fe2O3 were analyzed using XRD and FESEM techniques. From HR‐TEM study, particle size of PCz/CdS/α‐Fe2O3 nanocomposite was found to be 68.09 nm. The chemical composition and the binding energy of the elements present in PCz/CdS/α‐Fe2O3 nanocomposite were examined through XPS. BET studies revealed the mesoporous nature of PCz/CdS/α‐Fe2O3 with a large surface area (35.51 m2 g−1) compared to PCz/α‐Fe2O3 (21.52 m2 g−1) and PCz/CdS (7.47 m2 g−1) nanocomposites. Cyclic voltammetric studies revealed the highest specific capacitance (634.14 Fg−1) of ternary PCz/CdS/α‐Fe2O3 electrode in KOH electrolyte in comparison to H2SO4 (49.44 Fg−1) and Na2SO4 (79.94 Fg−1) electrolytes at a scan rate of 3 mVs−1. Cyclic stability test indicated a high capacitive retentivity of PCz/CdS/α‐Fe2O3 (97%) electrode than PCz/CdS (90%) and PCz/α‐Fe2O3 (93%) electrodes after completion of 2000 cycles. From EIS, PCz/CdS/α‐Fe2O3 displayed a low ESR value (1.35 Ω) than the binary electrodes; the value increased slightly after the cyclic stability analysis. All these indicate the effectiveness of PCz/CdS/α‐Fe2O3 as a suitable electrode for supercapacitors.
