摘　　要：采用水热法与电化学沉积法相结合的方式,以导电玻璃为基底制备不同MoO_(3)沉积周期的MoO_(3)/WO_(3)复合薄膜。利用电化学性能测试与光谱测试,得到了MoO_(3)/WO_(3)复合薄膜的电致变色可逆性、光密度值(ΔOD)、着色效率、稳定性和响应时间等性能参数。结果表明,电沉积8个周期MoO_(3)的MoO_(3)/WO_(3)复合薄膜与单一WO_(3)纳米棒薄膜和MoO_(3)薄膜相比具有最佳的电致变色性能,其电致变色可逆性为62.19%,光密度为0.61,着色效率为153.16 cm^(2)/C,着色和褪色响应时间分别为8.37 s和4.77 s,同时,具有更窄的带隙和更高的循环稳定性。MoO_(3)/WO_(3)composite films with different MoO_(3)deposition cycles were prepared to use conductive glass as the substrate by combining hydrothermal method and electrochemical deposition method.Electrochromic reversibility,optical density(ΔOD),coloration efficiency,stability and responding time of MoO_(3)/WO_(3)composite film were obtained by electrochomical measurement technologies and spectral tests.The results show that the MoO_(3)/WO_(3)composite film with 8 MoO_(3)electrodeposited cycles has the best electrochromic performance compared with single WO_(3)nanorod film or MoO_(3)film,and the electrochromic reversibility is 62.19%,the optical density is 0.61,the coloration efficiency is 153.16 cm^(2)/C,the coloring and bleaching responding time is 8.37 s and 4.77 s,respectively.It the meanwhile,it has a narrower band gap and higher cyclic stability.
