You should be fine just beware of new peaks that might show up e.g. I have seen that a peak shown up in the CV at around 0.3 - 0.5V during the oxidation cycle i.e. emeraldine phase.

Ebrahim Fooladi

yes. graphite can be used carbon paste electrode for polymerization. when used of cyclic voltametry between -.2-0.8 V it is imposible

Ahmed Bahloul

Yes you can use the graphite as working electrode in

CH3CN / 0.1M LiClO4 / 0.01M Py, range potential -0.2 to 1.1 V/SCE

H2O/ 0.1M Na2SO4/0.01M Pani, range potential -0.2 to 1.2 V/SCE
