“…Similarly, the FTIR spectrum of ternary PIN/PPY/CdS polymer nanocomposite showed the absorption peaks at 3425, 1634, and 937 cm −1 , which were attributed to NH, CC, and CN stretching vibrations of PIN, PPY, and CdS, respectively. The three characteristic peaks were also found to be shifted from their standard peaks positions, confirming the successful interaction between polymer PIN/PPY matrix and CdS nanoparticles 69 …”

A facile ternary nanocomposite comprising of polyaniline, titanium dioxide, polypyrrole, that is, PANI‐TiO2‐PPy was synthesized by in‐situ chemical oxidative polymerization method and fabricated as an active electrode material for supercapacitor applications. The phase, morphology, chemical composition, electronic states and thermal behavior of PANI‐TiO2‐PPy were analyzed using XRD, FESEM/EDAX, FTIR, XPS, and TGA techniques. CV profile of PANI‐TiO2‐PPy electrode exhibits the highest specific capacitance (600 F g−1) at 1 mV/s in 1 M KOH electrolyte, which is higher than the PANI (31 F g−1), PPy (120 F g−1), and TiO2 (398 F g−1) electrodes. The charge storage mechanism of PANI‐TiO2‐PPy electrode was also explored in 1 M H2SO4 and 1 M Na2SO4 electrolytes; wherein the capacitive behavior of ternary electrode was found to be superior in alkaline electrolyte compared to acidic and neutral electrolytes. From GCD, the ternary electrode exhibited the longest charge/discharge curve when compared to unary electrodes, which affirms the improved energy storage capacity of PANI‐TiO2‐PPy. The lower ESR value (0.90 Ω) exhibited by ternary electrode in comparison with PANI (1.75 Ω), PPy (1.59 Ω), and TiO2 (2.11 Ω) and 92% of capacitive retention after 2500 charge/discharge cycles suggest that PANI‐TiO2‐PPy could be a suitable active electrode for supercapacitors.

“…The peak at 1308 cm –1 belongs to the breathing vibration of the CN bond. The peak at 752 cm –1 is allocated to the C–H band (out-of-plane) deformation vibration. , The FTIR spectra of PANI/PIn showed that the peak at 3435 cm –1 may be due to the O–H and N–H stretching vibrations of water and aniline/indole. The peaks are present in pristine PANI and the PIn matrix, where all exist in the PAPI composite, which denotes that the PAPI composite consists of both compounds.…”

Supercapacitors have attracted extensive consideration due to their high power density and long cyclability. However, safety and flexibility have become tasks encountered by supercapacitors with the further increase in their demand. Herein, we report a carbon-quantum-dots-anchored poly(aniline-co-indole) (PAPI@CQDs) composite thin film fabricated by the hybrid electrospray deposition method. It was found that the PAPI@ CQDs composite film showed outstanding electrochemical performance with the highest specific capacity (C s ) of 185.1 C/g at 2 A/g with an excellent cyclability of 79.4% at 20 A/g after 10000 consecutive charge−discharge cycles. Finally, the proposed electrode can be used to fabricate a hybrid solid-state supercapacitor (PAPI@CQDs//rGO, where rGO = reduced graphene oxide). The fabricated PAPI@CQDs//rGO asymmetric supercapacitor (ASC) device showed the highest specific capacity of 84.2 C/g at 1 A/g with an ultrahigh energy and a power density of 26.22 Wh/kg and 1125 W/kg, respectively. The solid-state PAPI@ CQDs//rGO ASC device sustains outstanding cyclability, with a retention of 72.3% after 5000 cycles at 20 A/g. This study offers an effective tactic to attain conducting polymer-based composite electrodes for supercapacitors and extend their application in the field of flexible electronics.

“…In addition, Figure 8 a–f show the FE-SEM images of MnO 2 @CE/PPy at different magnifications. Polypyrrole was decorated on the top of the stacked MnO 2 and CE, which provided more surface area for adsorption and desorption kinetics [ 53 ]. The polypyrrole was responsible for inhomogeneous small semispherical grain-like structures [ 52 ] with a size of 15–30 nm.…”

Chemical warfare agents (CWAs) have been threatening human civilization and its existence because of their rapid response, toxic, and irreversible nature. The hybrid nanostructured composites were synthesized by the hydrothermal process to detect the dimethyl methyl phosphonate (DMMP), a simulant of G-series nerve agents, especially sarin. Cellulose (CE), manganese oxide cellulose (MnO2@CE), and MnO2@CE/polypyrrole (PPy) exhibited a frequency shift of 0.4, 4.8, and 8.9 Hz, respectively, for a DMMP concentration of 25 ppm in the quartz crystal microbalance (QCM). In surface acoustic wave (SAW) sensor, they exhibited 187 Hz, 276 Hz, and 78 Hz, respectively. A comparison between CE, MnO2@CE, and MnO2@CE/PPy demonstrated that MnO2@CE/PPy possesses excellent linearity with a coefficient of determination (COD or R2) of 0.992 and 0.9547 in the QCM and SAW sensor. The hybrid composite materials showed a reversible adsorption and desorption phenomenon in the reproducibility test. The response and recovery times indicated that MnO2@CE/PPy showed the shortest response (~23 s) and recovery times (~42 s) in the case of the QCM sensor. Hence, the pristine CE and its nanostructured composites were compared to analyze the sensing performance based on sensitivity, selectivity, linearity, reproducibility, and response and recovery times to detect the simulant of nerve agents.
