Electrochemical Polymerization of Schiff Base Transition Metal Polymer Poly[Ni(Salen)] and Its Electrochemical Performance in Organic Electrolyte

摘要

Poly[Ni(salen)] films were prepared by electrochemical polymerization with a constant potentialmethod onto a polished Ti substrate in an organic electrolyte system. Fourier transform infraredspectroscopy (FTIR) was used to characterize the specific chemical groups of poly[Ni(salen)] and fieldemission scanning electron microscopy (FESEM) was used to analyze its morphology andmicrostructure. The electrochemical properties of poly[Ni(salen)] were investigated by cyclic-1 voltammetry (CV) and galvanostatic charge-discharge (GCD) in 1 mol L Et3MeNBF4/AN solution.Furthermore, the influence of different polymerization time on the microstructure and electrochemicalperformance were compared. The results showed that the surface coverage of poly[Ni(salen)] on theanode substrate increased as the polymerization time extension, but its electrochemical activity wasgreatly limited. The poly[Ni(salen)] film prepared in the polymerization time of 1000s showed the-1 -1 highest discharge specific capacitance (73.5 Fg ) at a low current density of 0.5 Ag .
