The spectral response of polymer films derived from ring substituted arylamine compound during its cathodic relaxation, was studied, at room temperature, in the range 200-1000 nm, as a function of the wait time at potential value near the reduction potential of the polymer. It was employed an in situ technique, to measure the absorbance changes of PANI and POT, in different electrolytic media during polymer relaxation.
