The polymer of complex[Ni(salen)],(N,N’-ethylenebis(salicylideneaminato) nickel(H)),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 Et_3MeNBF_4/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.
The polymer of complex [Ni (salen)], (N, N’-ethylenebis (salicylideneaminato) nickel (H)) was prepared on graphite electrode by the route of linear sweep potential method. The nano-micro sheaf / wire structures of poly [Ni (salen)] has 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 Et_3MeNBF_4 / 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.
