Description
Technical field
The present invention relates to intelligent vehicle-carried apparatus field, particularly relate to a kind of Antiglaring rear mirror.
Background technology
Rearview mirror is one of indispensable accessory of automobile, can clearly reflect the situation of rear view of vehicle, side and lower section, so that driver can see the situation of these positions indirectly, expands the field range of driver. The surface configuration of rearview mirror has one layer of reflectance coating, it is possible to play the effect of direct reflection. But in some cases, such as vehicle travels under solar glare is irradiated, or vehicle is when night running, when front vehicle opens the strong illuminations such as high beam, the minute surface effect of rearview mirror can reflect extremely strong light, produce dazzle on the reflecting film, cause that driver does not see road conditions, affect traffic safety.
Electrochromism refers to that the phenomenon of stable, reversible color change occurs the optical properties (reflectance, transmitance, absorbance etc.) of material under the effect of extra electric field, shows as the reversible change of color and transparency in appearance. Electrochromic material is divided into inorganic electrochromic material and organic electrochromic material. The Typical Representative of inorganic electrochromic material is Tungstic anhydride. (WO3), at present, the electrochromic device industrialization being functional material with Tungstic anhydride.. And organic electrochromic material mainly has polythiophene class and derivant, purple sieve essence class, tetrathiafulvalene, metallo phthalocyanine etc.
Inorganic electrochromic material mostly is transition metal oxide or derivatives thereof, and the electrochromism phenomenon that first time finds is exactly the variable color of amorphous WO 3 film. Transition metal electronic shell is unstable, has not paired single electron to exist. The ion of transition metal generally has a color, and ground state and excited energy difference less, the reversible transition of valence state generation under certain conditions, form mixed valence ion coexisting state. With the change of ionic valence condition and concentration, also can there is corresponding change in color, here it is transition metal oxide possesses the reason of electrochromism ability.
Organic electrochromic film kind is relatively many, it is possible to be divided into organic molecule electrochromic material and the big class of conducting polymer electrochromic material two.
The Typical Representative of organic molecule off-color material is exactly purple sieve essence compounds, and such material there will be colour switching in oxidation-reduction process, so belonging to again oxidation-reduction type compound.Generally, middle condition purple sieve essence compounds makes intramolecule electron transfer be prohibited due to self structure particularity, and therefore color is shallower. Along with the raising applying current potential, middle condition structure changes to partial oxidation state gradually, ultimately generates stable dicationic forms, presents colourless under this state. Due to the light electrotransfer that intermolecular existence is strong so that univalent cation color is the deepest.
Conducting polymer electrochromic material is the class material that 20 century 70 new developments are got up. Hideki Shirakawas etc. have obtained very fast development since finding conduction polyacetylene. Since the eighties in 20th century, after demonstrating significantly high electric conductivity along with conjugated highpolymer through little molecular dopant and electrochromism phenomenon occur, conducting polymer just quickly grows up as electrochromic material. Such material comes into one's own because having the advantages such as expense is low, optical quality good, color conversion is fast, cyclic reversibility is good. The principle of conducting polymer variable color is mainly its doping process, and the essence of doping is the moving into and the behavior of moving out in macromolecular chain such as ion, the gain and loss of simultaneous electronics, and therefore the doping process of conducting polymer is a redox reversible process. The process of doping has caused the transition between molecule conduction band and valence band, including extremely sub-energy level, orphan's energy level, dipole energy level, electronics different energy level transitions, make spectrum that different change to occur. Controlling voltage within the specific limits and determine doping level, thus causing that the absorption of visible region is different, it is shown that the change of color, just there occurs electrochromism phenomenon.
