通过在紫罗精溶液中加入钛离子, 得到了一种新型互补型的电致变色溶液. 利用这种电致变色溶液设计成电致变色器件, 通过紫外-可见分光光度计表征, 这种溶液型电致变色器件透过率变化在600nm附近可由80%降低到20%; 通过电致变色器件和透射光强变化的关系, 测得其退色时间<2s, 并且具有自擦除效果.
A new coupling electrochromic solution was investigated by introducing titanium ion into viologen solution. The solution-based electrochromic device was assembled by using this coupling solution. The transmittance of this electrochromic device decreased from 80% to 20% in the wavelength of 600nm, which was characterized by UV-Vis spectra. The bleaching time of this electrochromic device was less than 2s and this electrochromic device had a character of self-erasing process.
