Electrochromic materials have been attached widespread attention due to their potential applications such as display

smart windows and military camouflag

etc. In this paper

the electrochromic mechanism of polythiophene and its derivatives is introduced. The electrochromic properties

research progress and its application of polythiophene

D-A material

D-A-D material

thiophene copolymer and organic/inorganic nanocomposite materials are reviewed. It is believed that the D-A/D-A-D material

thiophene copolymer and organic/ inorganic nanocomposite materials with multicolors

good stability and film forming properties

easy processing

good conductivity properties should be the mainly development direction.
