Description
Technical field
The present invention relates to a kind of electrochromic material, belong to automobile and use the anti-glare inner rear-view mirror field.
Background technology
Electrochromic device refers to that reversible variation occurs the optical property of off-color material under the outside alive driving, shows will occur painted on the color and variation that fade, can realize the purpose of light modulation according to painted and contrast that fade.Compare with traditional CRT display technique, electrochromic device has very low driving voltage; The characteristics such as color is adjustable.The particularly important is, electrochromic device super clearly contrast and broad visual angle will become one of main flow of paper type flat-panel monitor of new generation.In addition, because the change of electrochromic device color can be played the modulation to light, in auto industry, can be used for anti-dazzle driving mirror, in building construction as a kind of novel intelligent glass.
Electrochromic device generally comprises glass substrate, glue frame, electrochromic material, transparency conducting layer, conductive reflective.Because electrochromic material contains cathode electrochromic material and anode electrochromic material, and transparency conducting layer and conductive reflective are had certain corrosivity, therefore need transparency conducting layer and the certain corrosion resistance of conductive reflective needs.Generally select ITO at present transparency conducting layer, the ITO of doped with fluorine, ZnO, Zn
3In
2O
6, ITO/ metal/ITO (IMI) etc., materials belong to inorganic aspect, and corrosion resistance is better.Al has high reflectance in conductive reflective, but stability is poor, be easy to be subject to the corrosion of environment, generally seldom be used for doing independent conductive reflective, therefore conductive reflective is generally selected the metal alloy of silver alloy and so on, mainly be because silver has higher reflectivity, being coated on reflectivity on glass can arrive more than 98%, but silver is stable poor simultaneously, easily cohesion, apparent defective occurs, therefore have a lot of products and select silver alloy as the material of conduction reflectance coating.These materials mainly contain Ag/Au, and the alloy that the noble metals such as Ag/Pt or Ag/Pd form has higher stability, but because cost is higher, and just someone had added Cu or Ti or stainless steel afterwards, Ni etc. are used for improving stability, reduce cost.
Principle of work in electrochromic device provides electronics for conductive reflective, and transparency conducting layer provides the hole.In order to reduce driving voltage, just need to improve electronics and hole such as efficient.Therefore require the work function of anode.(least energy that work function refers to make an electronics to overflow and must provide from solid surface immediately) is high as far as possible, and the work function of negative electrode is low as far as possible.Anode generally is to adopt transparent metal (such as Au), transparent conductive polymer (such as polyaniline) and the ITO electro-conductive glass with high work function, and the material that brings disaster to that the most generally adopts is ITO, and the work function that it has is 4.7eV.The work function of above-mentioned silver alloy negative electrode is also relatively high, has reduced the injection efficiency of electronics.Cause that thus driving voltage raises, and makes the device accelerated deteriorations such as electrochromic device or LCD, hydraulic performance decline.
Summary of the invention
