Ionic thermoelectric materials, renowned for their high Seebeck coefficients, are gaining prominence potential in harvesting low-grade waste heat. However, the theoretical underpinnings enhancing performance of these materials remain underexplored. In this study, Hoffmeister effect was leveraged to augment properties hydrogel-based ionic materials. A series PAAm-x Zn(CF3SO3)2, ZnSO4, and Zn(ClO4)2 hydrogels were synthesized, using polyacrylamide (PAAm) as matrix three distinct zinc salts with varying anion volumes impart effect. Exceptionally, most cost-effective ZnSO4 yielded highest coefficient among hydrogels, PAAm-1 achieving a remarkable value −3.72 mV K–1. To elucidate underlying mechanism, we conducted an innovative analysis correlating ion transfer number. Additionally, hydrogel demonstrated outstanding mechanical properties, including elongation at break (>1400% its peak), exceptional resilience (virtually no hysteresis loops), robust fatigue resistance (overlapping cyclic tensile curves). This work not only advances understanding but also showcases practical heat recovery applications.
