Description
Technical field
The invention belongs to field of display technology, it is related to a kind of alkali responsiveness electrochomeric films and preparation method thereof and answers
With.
Background technique
Electrochromism is the optical properties of material, refer to stablize under external electric field or the function of current, reversible color becomes
Change, the process of reversible change occurs for the color and transparency that intuitively show as material.From foreign scholar's the 1960s
Since Plant is put forward for the first time electrochromism concept, electrochromism phenomenon, which causes, widely to be paid close attention to.It is existing using this electrochromism
As electrochromic device can be prepared.Electrochromic device have visual angle is wide, driving voltage is low, idle memory etc. it is unique excellent
Point herewith has extremely wide purposes in the rearview mirror etc. of sensitive window, display and automobile etc..Electrochromic material can divide
For inorganic and organic two class, inorganic electrochromic material has tungstic acid, Prussian blue etc., and organic electrochromic dyestuff is divided into again
Two class of small organic molecule and macromolecule, small molecular have purpurine, phthalocyanine etc., and macromolecule includes polyaniline compound, polythiophene class etc..
For electrochomeric films majority using ito glass as electrically-conductive backing plate, assemble method is broadly divided into two classes, Yi Zhongfang at present
Method is by electrochomeric films by being either physically or chemically deposited on electrically-conductive backing plate surface, and this method cost of manufacture is higher,
The difficulty for obtaining the uniform electrochomeric films of large scale is larger；Another method is that electrochromic material is dissolved in gel or liquid
It in body electrolyte, is filled among two panels electrically-conductive backing plate, although this technology cost of manufacture reduces, it can be difficult to producing big ruler
Very little, special shape optically variable films.CN101412588A discloses a kind of cathodic electrochromic film and electrochomeric glass
Preparation method, with H2WO4Powder or Ni (NO3) powder be raw material, using citric acid complex-polymerization liquid chemical method, immersion coating
Technique or spin coating coating processes obtain sol pellicle on ito glass substrate, obtain cathode electricity through dry polymerization, Low Temperature Heat Treatment
Optically variable films is caused, preparation method is complicated, and the electrochromism response time is longer and consumes energy more；" electroluminescent acid/base it is theoretical and its
It is mentioned in application in organic electrochromic material " and uses hydroquinone for electroluminescent alkali, novel oxazole quinoline molecule FXF is as soda acid
Response color indicator is prepared for electrochromic device, and the electrochromic device response time is short, but the stability of device is poor.
Currently, the electronical display huge energy consumption that the whole world is annual, year power consumption is more than 3.5 million degree of electricity, total close to whole world power consumption
The 19% of amount is equivalent to the year power generation total amount in 70 Yangtze River Gorges；And traditional electronic display screen is because of color flash and back
The stimulation of scape light, can cause irreversible injury to human eye.
Need a kind of low energy consumption, electrochromism response time short at present and the simple electrochomeric films of preparation method.
Summary of the invention
The purpose of the present invention is to provide a kind of alkali responsiveness electrochomeric films and its preparation method and application.
In order to achieve that object of the invention, the present invention uses following technical scheme：
On the one hand, the present invention provides a kind of alkali responsiveness electrochomeric films, the alkali responsiveness electrochomeric films
Including electrochromic layer, the electrochromic layer includes following component in parts by weight：
Wherein, the alkali response dyestuff is the combination of electroluminescent alkali and alkali responsive materials.
Electrochomeric films provided by the invention include electrochromic layer, and preparing for electrochromic layer includes alkali in raw material
Dyestuff is responded, after applying voltage, electroluminescent alkali occurs reduction (or oxidation) reaction and captures proton, and alkali responsive materials lose proton, hair
The variation of raw color, and this state still can be continued for a period of time after voltage removes；And after applying backward voltage, electricity
Alkali is caused to be oxidized (or reduction) release proton, alkali responsive materials in conjunction with proton, restore to original state by color；The present invention mentions
The electrochomeric films of confession include electrochromic layer, can be stablized under the action of extra electric field, reversible color becomes
Change, there is electrochromic property, after being stimulated by voltage, can constantly show information, therefore under the premise of not consuming energy
Have the characteristics that low energy consumption.
