摘　　要：用化学方法合成Schiff碱型的过渡金属络合物单体[Ni(Salen)],采用恒电位法在不同电位下合成了过渡金属聚合物Poly[Ni(Salen)],并对其进行了电化学性能与物理表征研究.当电位为1.2 V时制备的聚合物在恒电流充放电测试中小电流密度0.1 mA/cm2下容量可以达到62.4 mF/cm2,大电流密度下容量2.5 mF/cm2.场发射扫描电子显微镜法(FESEM)显示,聚合物Poly[Ni(Salen)]为一种由于细长的丝状体缠绕而产生的团簇状的颗粒结构.The transition metal complexes monomer Ni（Salen） was synthesized by chemical process,the poly[Ni（Salen）] were electropolymerized under different potentials by potentiostatic method,and the electrochemical performance and physical characterization were investigated.The poly[Ni（Salen）] which was electropolymerized under the potential of 1.2 V has better performance than those by the potentiostatic methods,its capacitance ranges from 62.4 to 2.5 mF·cm-2 at 0.1～10 mA·cm-2.The FESEM showed that the micro morphology of the poly[Ni（Salen）] film is a cluster-like granule structure with slender filaments winding.
