Embodiment
Please refer to Fig. 1, it is shown as the structural representation of a kind of electrochromic device 100 of the utility model at present.This electrochromic device 100 mainly comprises: one first transparent base 110; One first transparency conducting layer 120; One electrochromic layer 130; One second transparent base 140; One second transparency conducting layer 150; One auxiliary electrochromic layer 160; One electrolyte 170.Wherein, this first transparency conducting layer 120 is coated on the surface of first transparent base 110, forms one first electrically conducting transparent base material; Electrochromic layer 130 is coated on the surface of first transparency conducting layer 120; Second transparency conducting layer 150 is coated on the surface of second transparent base 140, forms one second transparent base; Assist electrochromic layer 160, be coated on the surface of second transparent base 140; And electrolyte 170, mix by an ionic liquid and a gum polymers, be filled in the first electrically conducting transparent base material that contains electrochromic layer and contain between second transparent base of auxiliary electrochromic layer.
First transparent base 110 and second transparent base 140 are selected from one of glass substrate, plastic base, flexible base plate; And the scope of the length 111 of first transparent base 110 and the length 141 of second transparent base 140 is between 1 meter to 2 meters, and wide 112 and 142 scope is between 0.5 meter to 1.5 meters.The difference of its assembly is that the conductive base that uses is different, if base material is all glass, is the penetration assembly, can be applicable to intelligent window and filter, and the number of light penetration amount can be by the current potential decision of conductive base.If base material simultaneously is a transparent conducting glass, another side is the light tight base material with reflectivity properties, is reflective assembly, can be applicable on rearview mirror or the display.
First transparency conducting layer 120 and second transparency conducting layer 150 are played the part of the role of conductive electrode in electrochromic device 100, provide the variable color process required electric current, therefore must adopt the transparent conductive material that has high penetration and high electrical conductivity concurrently.So, in this is novel, transparency conducting layer be selected from tin indium oxide (Indium Tin Oxide, ITO), aluminum zinc oxide (Aluminum Zinc Oxide, AZO), the fluorine doped tin oxide film (Fluorine Tin Oxide, one of FTO).Preferably, again because therefore fluorine doped tin oxide film (FTO) acid and alkali-resistance, heat-resisting, moisture-proof and the film forming raw material is cheap and production cost is low, use the fluorine doped tin oxide film in the utility model.In addition; The deposition process of first transparency conducting layer 120 and second transparency conducting layer 150 is selected from one of sputtering method, vapour deposition method, electrochemical plating, chemical vapour deposition technique, sol-gel process, spraying cracking process, infusion process, electrochemical process, and the thickness of film forming be 50 how rice to 300 how between the rice.
In the utility model, electrochromic layer 130 is selected from one of tungsten oxide, molybdena, titanium dioxide, niobium oxide, yttrium oxide usually.Wherein, preferably, attract most attention at present and the electrochromic material of widely research be tungsten oxide, because of it has high coloration efficiency (Coloration efficiency), reversibility is good, relative price is low, longest-lived and advantage such as nontoxic.Tungsten oxide film was found in 1969 has electrochromism property, and when its variable color mechanism was positioned at tungsten oxide for applying negative electricity, electronics and cation (or proton) were moved in tungsten oxide simultaneously, and generate M
