The PEO2000 nano-sized Ni(OH)2 sol was prepared by sol-gel method with Ni(OAc)2 and ethanol as precursor and PEO2000 as stabilizer in butanol. The thin films were deposited on ITO/glass by spin-coating method. The influence of the sol components on formation of such films was investigated, while the structure evolution and surface pattern of the doped NiO films during annealing were investigated by TG-DSC, XRD and SEM. The results of cyclic voltammetry and optical transmittance showed that the PEO-doped NiO films have good electrochromic and optical performance.

Key words: sol-gel, electrochromic, nickel oxide, doped, poly(ethylene oxide)
