Description

A kind of electrochomeric glass
Technical field
The invention belongs to ambetti technical fields, and in particular to a kind of electrochomeric glass.
Background technique
Current China building energy consumption accounts for about the 28% of social total energy consumption, and window is the main way of building energy loss Diameter, and keep the temperature, the simple glass mean heat transfer coefficient of thermal insulation difference be 3.5W/ (m2), K it directly results in China and averagely builds energy Consumption is 3 times of developed country or more.For this problem, Ministry of Construction's proposition to the year two thousand twenty, all new buildings all need to reach section The target of energy 65%, and the use of energy-saving glass is the inevitable choice for reaching this target.Electrochomeric glass is a kind of common glass The intelligent power saving glass that glass and electrochromic system combine, can change according to external environment, be changed by adjusting voltage or electric current Become glass colour, to achieve the purpose that active control arrives at indoor incident laser energy.On the one hand the sun spoke of windowpane is reduced It penetrates hot, adjusts indoor thermal environment, improve thermal comfort, reduce building energy consumption；On the other hand saturating by adjusting the visible light of glass Light rate controls illumination level, reduces dazzle, improves Interior Illumination Environment.
Electrochromic material is then active functional material, and optical characteristics (such as light transmittance, reflectivity) can be according to surrounding The variation of environment occurs the total injection and total extraction of ion and electronics, connects the optical characteristics of material by electric field action It is continuous, reversible, arbitrarily change, to realize that optical density is continuously adjustable, therefore, there is huge actual application prospect.From 1973 Year, S.K.Deb had found WO3Since electrochromism phenomenon, scientist has carried out a large amount of research and exploration to it.WO3Film because , optical density (OD) good with electrochemistry cyclic reversibility it is poor it is big, coloration efficiency is high, the response time is short, memory time and cycle life The characteristics such as long, are widely used in electrochromic intelligent window.
But existing WO3Thin-film material electrochromic property is also unable to reach optimal state, and it is logical that there is presently no discoveries It crosses magnetron sputtering method optimization film layer microstructure and improves amorphous WO3The related patents of thin-film material electrochromic property.
Summary of the invention

The present invention compared to the prior art, WO3Film surface is that crest structure can increase the contact surface with ion conducting layer Product, WO3It is the transport resistance that loose cavernous structure can reduce lithium ion, one side WO inside film3Film fades completely, adjusts Photosensitiveness can increase, another aspect WO3Adhesive force is strong, has extended cycle life；Simultaneously also by regulation refractive index, to control WO3 The electrochromic property of film.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the electrochomeric glass of one embodiment of the present invention.
Specific embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
In order to reach the purpose of the present invention, as shown in Figure 1, providing a kind of electricity in one of embodiment of the invention Photo chromic glass is caused, including the first substrate 1, the first conductive layer 2, photochromic layer 3, ion conducting layer 4, ion storage layer set gradually 5, the second conductive layer 6 and the second substrate 7, photochromic layer 3 are WO3Film, WO3The surface of film is blade shape structure, WO3The table of film Surface roughness is 1.6nm~4.6nm, WO3The inside of film is cavernous structure, and the porosity of cavernous structure is 1%~11%, WO3 Film with a thickness of 200~600nm, refractive index is 2.06~2.12.
Wherein, first substrate and the second substrate are transparent configuration, and first substrate is glass, and the second substrate is glass, ceramics Or plastics；First conductive layer and the second conductive layer are transparent conductive film, and the first conductive layer and the second conductive layer are ITO or FTO； Ion conducting layer is transparent material, and ion conducting layer is the inorganic compound containing lithium or the polymer containing lithium；Ion storage layer is Transparent membrane, ion storage layer are NiO film or Prussian blue film.
The present invention compared to the prior art, WO3Film surface is that crest structure can increase the contact surface with ion conducting layer Product, WO3It is the transport resistance that loose cavernous structure can reduce lithium ion, one side WO inside film3Film fades completely, adjusts Photosensitiveness can increase, another aspect WO3Adhesive force is strong, has extended cycle life；Simultaneously also by regulation refractive index, to control WO3 The electrochromic property of film.
The present invention has the WO of following three kinds of microstructures using DC reactive magnetron sputtering technique preparation3Film, and to it Optical property and electrochromic property compare, specific such as table 1.
1: three kind of WO of table3The optical property and electrochromic property of state
Statistics indicate that there is tungsten oxide film microstructure to have extended cycle life, but film layer is finer and close for the moment, Li+Migration resistance Power is big, and optical tune ability is poor；When with microstructure three, film layer is loose, Li+Migration resistance is small, and optical tune ability is good, but Film layer is excessively loose, causes film layer attachment poor, cycle life is low；When with microstructure two, film layer structure gas porosity is suitable, Both it ensure that metachrosis, optical tune ability is strong, in turn ensures electrochromism cycle life.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention Protection scope.
