I synthesized PEDOT through electropolymerzaition in 10% acetonitrile (v/v) and deionized water in the presence of LiClO4 and of course the monomer EDOT.
The reference electrode used is Ag/AgCl, the counter electrode was glassy carbon and for the working electrode (where the PEDOT was formed) i used a graphite sheet. The scan rate is 100mV/s.
I attached the pictures of the voltammograms as well as the electropolymerized PEDOT on the graphite sheet.
Thanks
Hi, you can first of all calculate the surface coverage, and then you need a profilometer to know the thickness. CV does not give you this info.

you can not determine the thickness of the electro-polymerized PEDOT//graphite sheet, from your voltammograms, only.
Also, in your (next set of the) voltammograms, try to reduce the VHigh (presetting) value.

Ioannis Samaras : Thanks for your response. So basically, what do I exactly need besides the voltammograms, because i think first i need to separate the Faradic current from the capacitive one, and then integrate the Faradic part and use Faraday law to get the mass of PEDOT deposited. Also, what is exactly the presetting value ?

Serena Carrara : Thank you for your reply. I will check if my lab have this instrument.
Cheers
Dear Bzainia Amir,
the VHigh value is, simply, the high Voltage value in the (VLow:VHigh, the presetting limits of the V-)window of your CV(s).
