Polypyrrole Hybrid Nanocomposite Electrode Materials with Outstanding Specific Capacitance

Energies, Journal Year: 2025, Volume and Issue: 18(5), P. 1304 - 1304

Published: March 6, 2025

This paper discusses the results of our investigation effect processing parameters on electrochemical properties poly(vinylidene fluoride) single-walled carbon nanotube sheets and PVDF-CNTs modified by solution cast polyimide coating, followed electrodeposition polypyrrole. The polyimide-coated single-wall sheet–PI/SWCNTs composite consists SWCNT PVDF (9:1) wt.% 0.1–1 polyimide. temperature varied from 90 to 250 °C. SEM images validated nanostructure, while EDX confirmed material composition. EIS analysis showed that electrode processed at °C polypyrrole has lowest bulk resistance (65.27 Ω), higher porosity (4.59%), highest specific capacitance (209.16 F/g), indicating superior ion transport charge storage. Cyclic voltammetry cyclic charge–discharge analyses revealed hybrid achieved a 655.34 F/g scan rate 5 mV/s, demonstrating excellent cycling stability over 10 cycles current density 0.5 A/g. In contrast, electrodes 180 decreased performance due in part structural densification low porosity. These findings underscore critical role temperatures optimizing PI/SWCNT composites, advancing their potential for next-generation energy storage systems.

Effect of coupling agent 2,3,4,5‐tetrafluorobenzoic acid modification on dielectric energy storage properties of PVDF/PMMA‐BaTiO₃ nanocomposite films

Polymer Composites, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 13, 2024

Abstract In this paper, the carboxylic acid modifier 2,3,4,5‐tetrafluorobenzoic (F4C) was used to modify BaTiO 3 (BT) nanoparticles, which acted as a coupling agent. The modified BT(F4CBT) polyvinylidene fluoride (PVDF), and polymethylmethacrylate (PMMA) were make nanocomposite films: PVDF/PMMA‐F4C‐BaTiO films. unmodified BT nanoparticles PVDF/PMMA‐BaTiO modification effect of F4C resulted in an increase amount β‐phase γ‐phase, decrease α‐phase, overall crystallinity PVDF‐based dielectric constant films reached maximum value 16.7 at frequency 100 Hz 4 wt% F4C, 40.3% higher than that content 2 showed lowest loss 0.055, 56.7% lower breakdown strength increased then decreased with content, highest 2800 kV/cm 55.6% charging density 20.65 J/cm 394% Highlights Modification ceramic properties film significantly improved. Maximum polarization charge/discharge greatly improved by agent modification.
