Abstract

This article emphasizes the importance of sustainable materials in energy storage research. These ionic polymer blends show potential as eco-friendly alternatives for practical energy storage systems. We synthesized three distinct compositions of ionic polymer blends (25/15/60, 30/15/55, and 35/15/60) using solution casting techniques. Our focus was on PVDF, PVP, and PVSA—ionic polymers that offer environmental advantages over traditional materials.

Objective: To address these issues, we propose the use of ionic polymer membranes. By reducing the demand for synthetic plastics, these membranes contribute to pollution reduction. Moreover, they offer economic and environmental benefits. Ionic polymers can also help limit carbon dioxide emissions.

Method: In our study, we created a blend of polyvinylidene fluoride (PVDF), polyvinylpyrrolidone (PVP), and polyvinyl sulfonic acid (PVSA). This blend was used to fabricate an ionic membrane through the solvent casting method. The resulting membrane acts as a successful dielectric material, sandwiched between copper electrodes. We conducted extensive characterization, including microstructure analysis, crystal structure examination, identification of functional groups, and thermal behavior assessment.

Results: Our findings demonstrate the potential of ionic polymer membranes for capacitor applications. By varying the composition of PVDF/PVP/PVSA, we explored different dielectric properties. Notably, the ionic polymer electrolyte can serve as an effective dielectric material, with copper electrodes providing a practical application.

Conclusion: Our investigation included electrical current density measurements using cyclic voltammetry, elemental composition analysis, morphological studies, and material composition assessments.
