What can be the possible cause of low value of impedance at lower freqency region in EIS experiments?

05 May 2023 1 3K Report

I have monitored EIS of inhibitor film-coated carbon steel substrate and found the impedance of this kind of impedance response. What can be the plausible explanation behind the variation in impedance at different ranges of frequencies?
