In Figure 3(b), Raman spectroscopy under 532 nm green light laser excitation provided the results correlated to the effect of acid on PEDOT chain with and without methanesulfonic acid treatment.
The increase in separation of anodic and cathodic peaks implied that the electron self-exchange in polymer films as a result of acid-induce behavior [30], whereas redox process (reduction and oxidation) can be indicated in the potential range of CV characterization after the methanesulfonic acid treatment.
