Detailed description of the invention
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
Electrochromism (Electrochronism/EC) refers under the effect of electric current or electric field, there is the phenomenon of stable reversible change in the optical properties (transmissivity, reflectivity or absorptivity) of material, just show as the reversible change of color and transparency so in appearance, then can regulate sunshine through number.The material with electrochromic property is called electrochromic material.Since the electrochromism phenomenon of Deb.S.K. Late Cambrian WO3 film in 1969, people have just found the material much with electrochromic property.Electrochromic material roughly can be divided into inorganic electrochromic material and organic electrochromic material by material type.The stable performance of inorganic electrochromic material, its light absorption change is because the Dual Implantations of ion and electronics and black soy sauce go out to cause.The light absorption change of organic electrochromic material is from redox reaction, and its rich color, easily carries out MOLECULE DESIGN, thus favored.
Electrochromic device is mainly divided into three parts: working electrode, to electrode, and electrolyte.Working electrode is generally the electro-conductive glass being coated with electrochomeric films and forms, the electro-conductive glass that electrode is then covered by the film (majority plays the effect of storage of ions) of cooperating electrode work is formed, in electrolyte, has the electrolyte of support performance electrode work.Whole device is similar to sandwich structure, working electrode and asking in being clipped in by electrolyte electrode, surrounding sealant sealing.When adding different driving voltage between two electrodes, the transmitance of device can change, and is generally change between clear state and coloured state.That is:, when adding a certain particular job voltage, device can be in pellucidity; When adding another particular job voltage, device can become colored state.By changing two interelectrode voltages, realize the change of device transmitance.
Why electrochromic material can show different colors under different driving voltages, is because redox state residing for it is different under different voltage, and then shows different band gaps, cause the change of color.
