摘　　要：本文利用阴极化电沉积法在抛光镍板及ＩＴＯ玻璃表面制备了含Ｃｏ量为１６．２％的ＮｉＯｘＨｙ薄膜，薄膜厚度分别为４２ｎｍ、２１ｎｍ，采用透射光谱以及线性电位扫描、交流阻抗和阳极稳态极化曲线等测试技术，考察了Ｃｏ对ＮｉＯｘＨｙ薄膜电致变色性能的影响，光谱测试范围为３００～２５００ｎｍ．结果发现：Ｃｏ能降低薄膜着色态在可见光区及部分近红外区的透过率，通过电压调节不仅可以调光而且可望能够控温；同时Ｃｏ还能降低ＮｉＯｘＨｙ薄膜电致变色电位，升高薄膜氧化着色过程中的氧析出过电位，对薄膜的电致变色性能有改进作用，但降低了着色过程中质子的扩散系数．Some effects of Co addition upon the electrochromic characteristics of a nic_kel hydroxide film were studied. The films were electrodeposited on both polished Ni plate and conductive ITO glass. The electrochemical behaviors were investigated using the film on Ni plate by linear potential sweep, a.c. impedance, and anodic polarization curves for OER(oxygen evolution reaction). It was found that Co can lower the working voltage and raise the oxygen overpotential, but has little effect on the reaction kinetics. It was also found that the Co can improve the optical properties of the electrochromic film.
