采用简单的两步法合成Schiff碱过渡金属单体Ni (salphen) 和Ni (CH3O-salphen), 再通过循环伏安法将单体电聚合到多璧碳纳米管 (MWCNTs) 上构成复合电极作为超级电容器正极材料.实验结果表明, 取代基甲氧基的加入使得Schiff碱过渡金属聚合物表现出更优的电化学活性并能够贡献更大的比容量, 材料的电化学性能得到明显的提升.此外, XPS分析表明储能是通过聚合物内活性基团在充放电过程中的可逆变化贡献的赝电容而不是Ni的变价贡献的容量来实现.“,”Schiff base transition metal monomers of Ni (salphen) and Ni (CH3 O-salphen) were synthesized with simple two-step method.The monomers were easily electropolymerized onto MWCNTs by cyclic voltammetry to form composite electrodes as the supercapacitor cathode materials.The experimental results show that the addition of the substituent methoxy groups into Schiff base transition metal makes the polymer exhibit better electrochemical activity and larger specific capacity, and the polymer material also obtains significantly improved electrochemical performance.In addition, XPS analysis results show that energy storage is achieved by the pseudocapacitance contributed by the reversible change of active groups in the polymer during charge and discharge, rather than by the capacity contributed by Ni valence change.
