Electrochemical performance of Ionic polymer metal composite under tensile loading

Abstract Cracks in polymer composites can lead to premature failure, which be disastrous for polymer-based energy storage devices. Detecting these cracks is essential guarantee the reliability and safety of such However, detecting composite polymers as ionic metal (IPMCs) a challenging task, makes it difficult ensure their performance safety. The overall goal this study investigate effect or damage caused by tensile loading on mechanical properties electrochemical characteristics IPMC based capacitors. During testing, deformation strips causes changes ion distribution concentration matrix, influencing material. measurements were conducted utilizing impedance spectroscopy at room temperature ( 21 ∘ C ) frequency range 10 KHz 1 Hz. method utilized proved easy quick with consistent results. capacitor was found increase its capacitance after major cracking Pt electrodes from high loads. Furthermore, lower (<100 Hz), real $\varepsilon ^{{\prime}}$?> ε ′ imaginary ^{{\prime} ^{\prime}}$?> part permittivity addition This displays that dielectric property material affected due increasing It concluded that, frequencies above 100 Hz, weakly load dependent.
