Exposure of reduced PEDOT to water extracted from agricultural soil. (a) Ion chromatography (IC) analysis of anions (see legend) present in the water samples (1 to 3) extracted from the field, (b) chemical analysis of treated PEDOTs using X-ray photoelectron spectroscopy (XPS), (c) atomic percentage of N absorbed by reduced PEDOT, and (d) calculated change of PEDOT’s sheet resistance after exposure to the extracted water samples 1 through 3.
