Another phenomenon that can contribute to nonideal capacitor behavior is electrolyte absorption into the polymeric coating . We speculate that this could also be occurring with our 3-scan DEB-coated system. This electrolyte absorption could also explain another feature of the equivalent circuit modelling results (Table ). We observed that 3-scan DEB-modified electrode had a significant decrease (by almost half) in the double layer capacitance compared to the bare electrode. If electrolytes were absorbing into the polymeric layer, it is possible that the overall permittivity could be reduced due to reduced polarizability, resulting in decrease in the observed double layer capacitance. The shunt capacitance (R2) also increased for 1-scan and 3-scan DEB coated compared to that of bare. More studies will be needed to understand these complex phenomena and verify these hypotheses.
