Abstract—Electrochemical Synthesis (ES)of polyaniline (PAni) is carried out in the presence in electrolyte (1
M H₂SO₄) of cerium (III) sulfate under potentiostatic and potentiodynamic modes. It is shown that Ce³⁺ cations
in electrolyte catalyze ES, i.e. accelerate both ES variants. The obtained polymers were characterized using the
scanning electron microscopy (SEM) technique and also on the basis of the calculation of electrochemical char-
acteristics. Relaxation in PAni polymers doped by the Ce³⁺ cation occurs several times faster than in proton–
doped PAni. The minimum change in E and E is observed in polymers doped by Ce³⁺ cations during the elec-
trochemical cycling of PAni and PAni–Ce at high rates.

Keywords: polyaniline, doping, electrochemical synthesis, induction period, relaxation
