Research paper thumbnail of Electrochemical synthesis of highly electroactive polydiphenylamine/polybenzidine copolymer in aqueous solutions

The composition of the copolymer and thus the electroactivity and conductivity of copolymer could be altered by variation of the comonomer feed ratios. The rate of copolymer formation is much higher than the homopolymerization. Electrochemical investigations indicate that reactivity of diphenyl amine for polymer formation is greater than that of benzidine, because of stability of diradical cations of benzidine. The copolymer which is formed under optimum conditions is much more eIectroactive than the corresponding homopolymers. Cyclic voltammetric studies show that the electroactivities of both benzidine and diphenyl amine moieties are apparent in copolymers.

The monomer used was diphenyl amine (DPA), and the electrolyte was HClO4. Cyclic voltammetry was used because the polymer formed by this method adheres tightly to the electrode and also deposits as a very smooth layer. The polymer was then used on the glassy carbon electrode in order to make a modified electrode for detection of vitamin C in urine. Different variables were studied in order to find the most suitable conditions for this electrode. Linear response of electrode to ascorbic acid concentration was very high with limit of detection of 0.2 ppm.
