Key Points

To develop an ionic hydrogel thermoelectric material exhibiting giant negative thermopower by tuning polymer-electrolyte coordination and hydration interactions.
Fabricated an ionic hydrogel composed of polyvinyl alcohol and sodium hydroxide using a dry-annealing process.
Modulated interactions between the polymer network and electrolyte ions to optimize thermoelectric performance.
Achieved a negative thermopower of up to −37.61 mV/K through synergistic coordination and hydration interactions.
Demonstrated an exceptionally high absolute thermopower relative to existing electronic and ionic conducting materials.
