“…As a kind of electrochromic material (ECM), conducting polymer has become one of the most important fields in functional material science due to its highly controlled conjugated molecular structure, flexible mechanical property, rapid response, excellent coloration efficiency and long life and many other specialties, which can be used widely in large-area display [1,2], storage devices [3], military camouflage [4], smart windows [5], anti-glare mirrors for cars [6] and so on. Among those conducting polymers, polyaniline (PANI) have attracted more and more attentions because of their adjustable conductivity from insulating to conducting range by a reversible doping and de-doping process [7].…”
