Description
Technical field
The present invention relates to electrochromic device, more particularly to solution type electrochromic rearview mirror, but it is not limited only to the electroluminescent change of solution-type
Color rearview mirror, also comprising solid-state and semisolid type electrochromic rearview.
Technical background
Electrochromism refers to the reversible change of the color that material occurs under extra electric field and transparency, and this change is due to material
Expect the optical properties (transmissivity, reflectivity or absorptivity) in ultraviolet, visible ray or near infrared region under DC Electric Field
Generate the reversible change of stabilization and cause.
Electrochromic device is that one kind can be by changing self color and then changing overall transmissivity or reflectivity under extra electric field
Device, it is the device for being aided with other relevant layers or material and constituting based on electrochromic material.Electrochromic device
Can be divided into 3 classes according to structure.One class is solution type electrochromic device；Wherein, electrochromic material is dissolved in electrolysis all the time
In liquid, electrochromic material is typically organic molecule.Equations of The Second Kind is half solution-type electrochromic device；Device in coloured state and
Along with the transmission and the change of materials chemistry property of electronics during being changed between clear state.When device is in pellucidity,
Electrochromic material is dissolved in electrolyte；When device is in colored state, electrochromic material can be in electrode surface enrichment simultaneously
It is covered in electrode surface and forms thin film.Usual this kind of electrochromic material is aromatics viologen compound, contains methoxyl group
Compound of fluorene class etc..3rd class is full-solid electrochromic device；During the entire process of device discoloration, electrochromic material begins
Solid state is in eventually.Usual this kind of electrochromic material is metal oxide, purpurine Prussian blue, containing organic acid group
And conducting polymer etc..Wherein, solution type electrochromic device has simple structure, preparation technology simplicity and response time short
The features such as, so the always focus of electrochromic device research.
The mode of operation of electrochromic device has transmission mode and reflective-mode.The main application fields of transmission mode are electrochromism
Smart window.The smart window that spectral characteristic according to electrochromic material makes is selectively passed through and absorbed by solar radiation,
Can efficiently control by the spectrum and energy of window, reach the purpose for making soft indoor light, amenity and reducing energy consumption；

The humidity of about 0% to about 100% scope, further, it is necessary to undergo under these temperature and humidities up to 100000 times colour fading
Circulation.Used as the part in solution type electrochromic device, it plays the conductive layer, anti-separated in front and rear substrate to adhesive
The only effect such as electrochromic solutions leakage, the influence of blocking oxygen, vapor and other dangerous vapors to electrochromism liquid.Therefore,
The quality of the sealing effectiveness of adhesive plays the effect of key to the service life of electrochromic device, security and performance etc..Mesh
Before, the method for comparing the sealing effectiveness of extreme detection adhesive is, at 121 DEG C, to be surveyed under the saturation high-pressure steam of 14~16psi
Examination 168 hours, whether detection electrochromic device is intact after having tested.
In Organic adhesive, epoxy resin adhesive occupies topmost status.US6714334 is disclosed by asphalt mixtures modified by epoxy resin
Fat (including bisphenol A epoxide resin, bisphenol F epoxy resin and novolac epoxy resin) and curing agent (including double (aminocyclohexyls
Base) methane, aliphatic cyclic amine and double (alicyclic ring) amine) composition for electrochromic device sealing adhesive.But epoxy resin
Hydrothermal stability it is poor, particularly under the high temperature conditions easily by electrochromic material erosion make adhesive property fail lead
Cause electrolyte leakage, the requirement therefore, it is difficult to meet the long-term use under severe rugged environment.
Additionally, in automatic color-changing rearview mirror, reflecting layer be usually white gold, silver or silver and other metals (such as gold, chromium,
Ruthenium, platinum, rhodium and palladium) formed alloy.But, in actual applications, there is adhesive and above-mentioned metal adhesion difference asked
Topic.It is probably that the above-mentioned metal or alloy of reason is difficult to form stronger chemical bond with adhesive.
