采用水热法和电聚合法相结合的方法制备了TiO2@PANI核/壳纳米棒阵列。具有显著的光学调制C-1）、良好的循环性能（1000次循环后62.1%）（700 nm处57.6%）、高的着色效率（37.1 cm（2））。其电致变色性能的改善主要归因于纳米棒的核/壳结构、给体-受体体系的形成以及纳米棒之间的多孔空间，这些结构可以降低氧化电位，使离子扩散更容易，并为电荷转移反应提供更大的表面积。这些数据表明TiO2@PANI核/壳纳米棒阵列作为潜在的电致变色材料具有很大的前景。
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.
