Figure 2. Thermogalvanic mechanism and microscopic interactions in the P(AAm-AMPS) electrolyte. (A) Schematic illustration of the thermogalvanic mechanism in a Fe(CN)64-/3--based thermocell; (B) Thermopower of P(AAm-AMPS) electrolytes as a function of the AAm/AMPS mass ratios; UV-vis spectra of (C) K3Fe(CN)6 and (D) K4Fe(CN)6 solutions with and without AMPS; (E) Schematic illustration of the microscopic interactions between AMPS segments and redox ions. AAm: Acrylamide; AMPS: 2-acrylamido-2-methylpropanesulfonic acid; UV-vis: ultraviolet-visible.
