Abd-Elrahman El-Naggar

i think this is depending on the polymerization conditions

Kim Mckelvey

This would suggest that the electrode area is changing due to the polymerization.

Can you give the continous scan segment number ?

Lavaraj Devkota

The lowest one is first cycle followed by upper ones. Scan was done in voltage range of 0 t0 0.8 @ 10 mV/S

Lasse Murtomäki

Kim's reply above is right. The same happens also with metal deposition, i.e. during nucleation.
