Dear all,
I have grown polyaniline film on stainless steel plate using electrodeposition technique by various current densities.
I want to know which is the best coating in terms of electrical conductivity. cyclic voltammetry is good option to see current carrying capacities ? what is the potential window for the CV ?
Thank you,
Regards,

There are several ways in which you can measure conductivity of these type of samples, such as four point probes, electrochemical field transistors, impedance measurements, etc. However, if you are doing any measurements in the presence of an electrolyte, you must consider carefully the effects of pH and applied potential, as these have a significant effect on the conductivity of conducting polymers such as polyaniline. In terms of the potential window for CV measurements, it will highly depend on your solvent and electrolyte for the reasons mentioned above.
Hi!
I think the best technique you can use is the Electrochemical Impedance Spectroscopy.
With the use of this ac technique with a three electrodes set up you can characterize the dielectric slab covering your electrode surface in terms of resistance and capacitance.
Dear Daniela and Lucia,
Thanks for your kind help. I will go with EIS and Four probe measurement.
