Description
Technical field
The invention belongs to technology for coating fields, are related to a kind of preparation method of electrochromism film.More particularly to a kind of benefit
It with flaky material after the electrically charged processing in surface, is aligned under the conditions of extra electric field, to realize electrochromism tune
The preparation method of optical coating.
Background technique
Light modulation film is often referred to be coated among two layers of conductive film using polymer dispersed liquid crystals (PDLC) composition, In
The translucency of film layer changes when applied voltage, to realize intelligent dimming function.PDLC composition and coating curing work
Skill is core.Polymer dispersed liquid crystals (Polymer DispersedLiquid Crystal, abbreviation PDLC) be a kind of liquid crystal with
Droplet form is dispersed in the Liquid Crystal/Polymer composite material in polymer matrix, it is with electric field-tunable control and well
Electro-optical characteristic, relative low price is easy to process, and is widely used, can be used as electrooptical window, liquid crystal light threshold, phase grating,
Hologram recording film etc. is the hot research topic of current field of display technology.
It is generally believed that the working principle of PDLC is: PDLC is made of polymeric matrix and liquid crystal droplet, wherein the light of liquid crystal
Axis has electric field-tunable control, and when adding enough driving voltages, liquid crystal optic axis is presented one along direction of an electric field by electric field action
What is caused is arranged in parallel, so that the liquid crystal molecule optical axis direction in all liquid crystal droplets is consistent, liquid crystal droplet and polymer at this time
Refractive index reaches exact matching state, does not scatter between high molecular polymer and liquid crystal molecule, therefore light transmission rate increases, such as
Fruit extra electric field field strength is sufficiently big, and vertical transmitance is up to maximum, is ON state；When extra electric field disappears, due to liquid crystal point
Anchoring between son and high molecular polymer interface acts on, and liquid crystal molecule optical axis is mixed and disorderly, and all droplets are also unordered arrangement, by
There is stronger optical anisotropy and dielectric anisotropy, the ordinary refraction index and polymer of liquid crystal droplet in liquid crystal molecule
Refractive index mismatch, therefore scattering process occurs between droplet and high molecular polymer mutually, the at this time vertical transmitance pole of incident light
Low, PDLC appearance is opaque milky white state, as OFF state.Application based on PDLC, due to basic research and technique
The reason of condition, equipment aspect, it is difficult to realize commercialization.Wherein PDLC relatively high driving voltage becomes it and is difficult to realize quotient
One of the reason of industry, thus become in holding contrast with the driving voltage that can effectively reduce PDLC while the response time
The a big difficulty and hot spot of PDLC photoelectric properties are improved, but the current technique improvement method for driving voltage focuses primarily upon liquid
Brilliant chemical synthesis replacement, the research of film-forming process or the change of driving method with polymer itself, these methods are to material light
Electrical property has a degree of improvement, but preparation process is complicated for operation, also higher to equipment requirement.
Currently, the development with advertising sector is more and more rapider, the bottom plate of advertising display have wooden boards, plastic plate,
Advertisement is directly be easy to cause serious resource wave using modes such as spray printing or brushings by Wood plastic boards, sheet metal etc., tradition
Take, replacement advertisement also carries out the processing such as cleaning, time-consuming and laborious and inconvenient.The heat-resisting quantity poor (one of liquid crystal material again
As long-term use temperature be no more than 70 degree), poor (generally long-term ultraviolet ageing does not surpass for the anti-ultraviolet ageing performance of organic resin material
Spend 2 years) etc. reasons, common PDLC light modulation film is suitable only for indoor partition etc., and is not suitable in the strong ultraviolet exterior window ring of high temperature
Border is used for a long time, and constrains application field significantly in this way.
