Aromatic polyamides (N-a, a=I-III) containing disulfide bonds and pyridine rings in the polymer backbone are prepared by condensation of diacid, 6,6’-dithiodinicotinic acid (N) and the corresponding alkyl diamine (a=I-III : NH2-(CH2)n-NH2, n=4, 6, 12) with interfacial polymerization technique. Electrochemical behavior of the polyamides is investigated by using polyamide carbon paste electrodes. All polyamides show the redox response due to cycling between disulfide and thiol (thiolate) in acetonitrile solution containing 0.1 mol dm(-3) LiClO4. The redox response is remarkable and the capacity is high in acetonitrile electrolyte solution. Polyamides N-I, N-II and N-III, shows good cycleability and high utilization to their theoretical values. The N atom in the pyridine ring is effective for redox reaction of the disulfide bond in the polymer. The capacity of the N-II/graphite electrode at first cycle is 93 Ah kg(-1) and utilization of the polymer is 67% of the theoretical value.
