| Outline of Final Research Achievements |
Electrochromism is a process by which the color of a materials is changed through an electrochemical reaction. The ability to reversibly change the absorption of electrochromic materials has aroused interest for application in technologies such as smart windows, and electronic papers. In this study, a multicolor reversible electrochromism was achieved in a potential engineered film. Cationic polymer containing ruthenium complex p(CM/Ru) and anionic Prussian blue(PB) nanoparticles were assembled based on their redox potential using the Layer-by-Layer deposition technique. The copolymer p(CM/Ru) works as a mediator for PB oxidation. The mediation of p(CM/Ru) enables to produce PB and its oxidized form of Prussian yellow in the same time. Moreover, the mixed state was returned to the initial form using O2 as a reduction mediator.
