摘要：

The TiO2@PANI core/shell nanorod array is prepared by the combination of hydrothermal and electropolymerization methods. A significant optical modulation C-1), and good cycling performance (62.1% after 1000 cycles) (57.6% at 700 nm), high coloration efficiency (37.1 cm(2) are achieved for the TiO2@PANI core/shell nanorod array. The improved electrochromic properties are mainly attributed to the core/shell structure, formation of the donor-acceptor system, and the porous space among the nanorods, which can reduce the oxidation potential, make the ion diffusion easier and provide larger surface area for charge-transfer reactions. The data indicate great promise for the TiO2@PANI core/shell nanorod array as a potential multicolor electrochromic material.
