摘要

The nanocomposite films were prepared by direct intercalation of poly(ethylene oxide), PEO, into V_2O_5 xerogel via sol-gel route. The electrochromic behavior was investigated by cyclic voltammograms and optical spectral transmittance. The results show that the cycleability and the cycling stability of insertion/extraction of Li~+ ions were improved and the transmittance in the visible and near infrared region was increased in (PEO)_(0.5)V_2O_·nH_2O nanocomposite film. The intercalation of PEO into V_2O_5 interlayer weakened the cathodic electrochromic characteristics and improved the anodic electrochromic characteristics.
