Figure 9: Impedance differences between only applying the treatment (bare carbon exposed) and with the addition of PEDOT:pTS.
In all cases, the addition of PEDOT:pTS decreases the impedance by an order of magnitude. Sample size: Nd:YAG = 262, Blowtorch = 262, UV = 7. UV sample size difference is due to the novelty of the preparation method; however, it shows a similar range to blowtorch, as expected. Impedance data are expressed as mean ± standard error. Abbreviations: PEDOT:pTS = poly(3,4-ethylenedioxythiophene):p-toluenesulfonate; Neodymium-doped yttrium aluminum garnet.
