ELECTROCHEMICAL POLYMERIZATION OF NANO-MICRO SHEAF/WIRE CONDUCTING POLYMER POLY[Ni（SALEN）] FOR ELECTROCHEMICAL ENERGY STORAGE SYSTEM

The polymer of complex [Ni（salen）], （N,N＇-ethylenebis （salicylideneaminato） nickel（U））, was prepared on graphite electrode by the route of linear sweep potential method. The nano-micro sheaf/wire structures of poly[Ni（salen）] have been obtained by adjusting the polymerization sweep rate of 5, 20 and 40 mV.s-1. The polymer prepared at 20 mV.s-1 had nanoscaled wire structure of ca. 100 nm in diameter. The good electrochemical reversibility of poly[Ni（salen）] was investigated by cyclic voltammetry and galvanostatic test in 1.0 mol/L Et3MeNBF4/acetonitrile solution. The initial specific gravimetric capacitance of poly[Ni（salen）] at the current density of 0.1 mA·cm-2 reached 270.2 F·g-1, however, the cycle stability needs to be improved.
