摘　　要：研究采用经济高效的溶胶-凝胶(Sol-gel)法制备三氧化钨(WO_(3))电致变色材料,设计正交实验,探究不同H_(2)O_(2)用量、反应温度及热处理温度对制备WO_(3)电致变色薄膜的影响因素大小。结果得出对WO_(3)薄膜性能影响大的因素是热处理温度及过氧化氢用量。继续探究在不同热处理温度下氧化钨电致变色薄膜循环耐久性。采用紫外-可见分光光度计、电化学工作站联用测试WO_(3)薄膜的电致变色性能。结果表明所制备的薄膜变色范围最高可达到60%以上,并且在200℃热处理的薄膜在循环1000圈后,变色范围还能达到45%以上。研究对于采用溶胶-凝胶法制备电致变色性能优异的WO_(3)薄膜有参考意义。In this research,the cost-effective sol-gel method is used to prepare tungsten trioxide electrochromic materials.Orthogonal experiments are designed to explore the influence of the factors on the electrochromic properties of the tungsten oxide film.The dosage of hydrogen peroxide,reaction temperature and post-annealing temperature are considered as the Taguchi factors.The results show that the post-annealing temperature and the dosage of hydrogen peroxide have stronger influence upon electrochromic properties of tungsten trioxide film.Then we continue to explore the circulation durability of tungsten trioxide films under different post-annealing temperature.The electrochromic performance of tungsten trioxide thin films is measured by UV-Vis spectrometer and electrochemical workstation.XRD patterns show the amorphous nature of the tungsten trioxide films.The optimized tungsten trioxide films annealing at 200℃exhibit a large modulation of optical tromsmittance more than 60%,which still stay above 45%after 1000 cycles.This study is useful for the preparation of tungsten trioxide films with great electrochromic performance by sol-gel method.
