A covalently bonded WO/PEDOT hybrid nanorods array has been prepared through solvothermal, oil bath, and electrochemical deposition methods using KH57 as a coupling agent. The obtained WO/PEDOT shows substantially increased electrochromic performance with an increased response speed (3.4 s for coloring and 1.2 s for bleaching), excellent optical modulation (86.7% at 633 nm), high coloration efficiency (122.0 cm/C at 633 nm), and distinguished cyclic stability. It was found that the covalent bond interaction between WO and PEDOT plays an essential role in property enhancement. The covalently bonded inorganic/organic hybrid nanorods array may promise great potential in developing smart-display and energy-efficient materials and devices featuring low energy consumption, cost effectiveness, and environmental protection.
通过使用KH57作为偶联剂，采用溶剂热法、油浴法和电化学沉积法制备了一种共价键合的WO/PEDOT混合纳米棒阵列。所制备的WO/PEDOT表现出显著增强的电致变色性能，具有更快的响应速度（着色3.4秒，漂白1.2秒）、优异的光学调制（633nm处为86.7%）、高显色效率（633nm处为122.0cm/C）以及出色的循环稳定性。研究发现，WO和PEDOT之间的共价键相互作用在性能增强方面起着至关重要的作用。这种共价键合的无机/有机混合纳米棒阵列在开发具有低能耗、成本效益和环境保护特点的智能显示及节能材料与器件方面可能具有巨大潜力。
