Fig. 2: Characterisation of conductive PEDOT:PSS.

a Size distribution of particles in aqueous dispersions of conductive PEDOT:PSS with 0, 2, 5, and 10 mg mL−1 ION E additive. b Normalised resistance of PU//conductive PEDOT:PSS films during elongation. c Crack onset strain values of PU//conductive PEDOT:PSS films with different amounts of ION E. d Raman spectra of PEDOT:PSS electrodes with different amounts of ION E, with an emphasis on the Cα═Cβ peak shift. e UV–vis absorption spectra and (f) GIXRD patterns of conductive PEDOT:PSS films with different amounts of ION E.
