通过在紫罗精溶液中加入钛离子,得到了一种新型互补塑的电致变色溶液．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． By adding titanium ions to the solution of violet, a new type of plastic electrochromic solution was obtained. Using this electrochromic solution as an electrochromic device, characterized by an ultraviolet-visible spectrophotometer, the transmissivity of such a solution-type electrochromic device can be reduced from 80% to 20% around 600 nm; the electrochromic The relationship between the device and the change of transmitted light intensity was measured, the fading time was less than 2s, and self-erase effect was obtained.
