Its polymer films are formed by electropolymerization from a AN/THF solution containing 0.1 mol/L LiClO 4, 0.1 mol/L HCl and 0.05 mol/L DAPD monomer on Pt electrode under continuous cycling between -0.30 V and 1.20 V vs . Ag/AgCl (sat. KCl) at scanning rate 50 mV/s. The cyclic voltammetry shows that its electrochemical behavior is similar to that of polyaniline. The redox peak current of the cyclic voltammograms increase with increasing of the cyclic times. The electronic conductivity of poly (DAPD) can reach from 2.1×10 -3 to 8.7×10 -3 S/cm. Two main facts are considered to be necessary for obtaining electroactive poly (DAPD) in electropolymerization process. One is the existence of sufficient concentration of the supporting electrolyte to enhance the ionic conductivity of AN/THF solution and the other is the existence of protons from the acid HCl. With an increase in acid content of the solution, the polymerization efficiency as well as the electroactivity of poly (DAPD) films show a striking enhancement and the electronic conductivity of poly (DAPD) film increases. But the concentration of HCl would be quite high to result in the decomposition of DAPD monomer.展开更多
