“…The slightly lower stability of PPy/GO-HT-1:1 compared to the other composites could be related to the facilitated penetration of electrolyte ions into the electrode porous structure (Figure 6b). The PPy/GO-HT hybrids present very good long-term performance compared to other previously reported PPy and graphene-based materials in an aqueous electrolyte (Table S1) [21,31,42,46,47].…”

“…The results of the EIS measurements in the form of the Nyquist plots are presented in Figure 5d for the PPy/GO-HT hybrids and in Figure S4 for their precursors. The solution resistance (R s ) determined from the intercept of the Z axis for all materials is in the range of 0.07-0.17 Ω [41,42]. However, significant differences between the binary materials are observed in the high frequency region of the Nyquist plot.…”

Herein, we propose hydrothermal treatment as a facile and environmentally friendly approach for the synthesis of polypyrrole/reduced graphene oxide hybrids. A series of self-assembled hybrid materials with different component mass ratios of conductive polymer to graphene oxide was prepared. The morphology, porous structure, chemical composition and electrochemical performance of the synthesized hybrids as electrode materials for supercapacitors were investigated. Nitrogen sorption analysis at 77 K revealed significant changes in the textural development of the synthesized materials, presenting specific surface areas ranging from 25 to 199 m2 g−1. The combination of the pseudocapacitive polypyrrole and robust graphene material resulted in hybrids with excellent electrochemical properties, which achieved specific capacitances as high as 198 F g−1 at a current density of 20 A g−1 and retained up to 92% of their initial capacitance after 3000 charge–discharge cycles. We found that a suitable morphology and chemical composition are key factors that determine the electrochemical properties of polypyrrole/reduced graphene oxide hybrid materials.

“…Then, 0.5 g of pyrrole was poured into the solution. After that 80 mL of 1.0 M FeCl 3 solution was poured instantly into the solution and then the solution was stirred for 12 h. 40 Over the whole experiment, the temperature was maintained between 0 °C and 10 °C. 24 After that, a black precipitate of polypyrrole was obtained and washed with ethanol and dried for 12 h at 60 °C.…”

Herein, a novel combination with a focused morphology is designed after synthesizing CrVO4 (CV) nanoparticles and poly‐pyrrole nanotubes (PNT or P) to prepare the interlocks of the composites of PNT and CrVO4 as 1PCV1, 1PCV2, 2PCV1, and 2PCV2 to study the supercapacitor application. Structural and spectral characterizations are perpetuated to confirm the synthesis of the samples. Results furnishing best energy storage are obtained for the intercalated composite 2PCV1 examined for three‐probe and two‐probe set‐up. The excel values for specific capacitance (Cs) for 2PCV1 concerning the Cyclic voltammetry (CV) cycle and Galvanostatic Charge Discharge (GCD) curve are 1745.60 F g−1 at 10 mV s−1 rate and 1545.62 F g−1 at 0.625 A g−1 current density studied along with interface controlled and transport‐controlled Cs with a contribution of 55.13% interface part and 44.87% transport part at 5 mV s−1 scan rate. Electrochemical Impedance Spectroscopy (EIS) study has provided 0.86 n‐factor with solution resistance Rs of 1.48 Ω, and a charge transfer resistance of 0.166 Ω. The respective specific power and specific energy values obtained through the two‐probe set‐up are also interestingly high 416.68 W kg−1 and 45.14 Wh kg−1 at 0.83 A g−1 current density. Also, the retention % in Cs values is studied by running 5000 continuous voltammetric cycles with 96.23% retention in supercapacitor device.
