Description
Technical field
The present invention relates to liquid crystal material technical field more particularly to a kind of quick response polymer based on hyperbranched monomer
Stabilized cholesteric phase liquid crystal light valve and preparation method thereof.
Background technique
Currently, liquid crystal material has been widely applied in conventional display device field.With the development of science and technology and people
Improvement of living standard, said three-dimensional body is shown and the wearable popular direction shown as display device.
The display body of said three-dimensional body display system is made of multilayer liquid crystal light valve, by circuit drives liquid crystal light valve is existed
It is switched fast between scattering states and transparent state, it is steady that the refresh rate of light valve need to reach the picture that at least 48Hz or more could make
Determine flicker free；Further, since image need to pass through multilayer liquid crystal light valve, therefore light loss is very serious, and brightness reduction then will lead to figure
As smudgy clear；Therefore, said three-dimensional body display system needs the light valve of a kind of high transmittance and quick response.
And polymer stabilizing cholesteric phase (Polymer-stabilized Cholesteric Texture, PSCT) liquid crystal light
There is valve relatively high transmitance, biggish visual angle, faster response speed can realize that said three-dimensional body is shown.
The response time of PSCT liquid crystal light valve significantly affects the image quality that body is shown.It is not powered on PSCT liquid crystal
Light valve is in Focal conic state, then causes nematic state in field after power-up, the twisting resistance that the chiral agent in liquid crystal compound generates with polymerize
The anchoring dynamic balance that object network generates makes PSCT liquid crystal light valve be in stable Focal conic state, PSCT liquid crystal light valve rise time master
Electric field strength is depended on, and fall time then depends on chiral agent and is anchored to the twisting resistance and polymer grid of liquid crystal to liquid crystal
Relationship of vying each other between power, polymer network anchorage force have very important influence to the PSCT liquid crystal light valve response time.
But have the research to the PSCT liquid crystal light valve response time, focus mostly in by change polymer monomer type,
The monomer cure temperature and intensity of ultraviolet light carrys out the optimizer response time when solidifying.For example, bibliography (quick response light valve

Valve improves the response speed of PSCT liquid crystal light valve by introducing hyperbranched monomer in its liquid crystal compound precursor, weaken its
The granular sensation phenomenon occurred in imaging process.
Specific technical solution is as follows:
A kind of quick response polymer stabilized cholesteric phase liquid crystal light valve based on hyperbranched monomer includes liquid crystal mixing
Object is calculated in mass percent, and is contained in liquid crystal compound precursor:
Liquid crystal compound precursor forms liquid crystal compound after photocuring.In Light Curing, acted in particular light
Under, photoinitiator causes hyperbranched monomer and liquid crystal monomer polymerization, forms polymer, liquid crystal and chiral agent are anchored at polymer
Grid in.
The liquid crystal monomer be 4- (3- acryloxy propoxyl group) benzoic acid 2- methyl-1,4- phenyl ester (RM257), 1,
Bis- [4- (6- acryloxy hexyloxy) the benzoyloxy] -2- methylbenzenes (RM82) of 4-.
The hyperbranched monomer is the acrylic ester monomer of 3~8 functional groups.
The liquid crystal monomer polymerization that is introduced as of the hyperbranched monomer provides node, so that polymer network is more equal
Even, grid defect is reduced, and uniform polymer grid reduces its anchoring to liquid crystal so that PSCT remove electricity after liquid crystal in chirality
Faster restore from vertical TEXTURE STATE (H state) to conical texture state (FC state), and uniform polymeric web under agent effect
Lattice can make PSCT scattering states multidomain structure more uniform, and scattering imperfection reduces, and effectively weaken imaging particle sense problem.
Preferably, in the liquid crystal compound precursor, the gross mass percentage of hyperbranched monomer and liquid crystal monomer is 4.5
~6%.If monomer total amount is excessively high, monomer polymerization formation polymer network anchorage force is too strong, and liquid crystal cannot restore from H state to FC
State；If monomer total amount is too low, monomer polymerization forms polymer and has just fallen anchorage force deficiency, and liquid crystal is in chiral power and polymer grid anchor
Determine to be difficult to maintain FC state under the competitive relation of power, PSCT scattering strength is greatly reduced.
Further, in the liquid crystal compound precursor, hyperbranched monomer mass percentage is 0.2~0.6%, over-expense
It is too low to change content of monomer, it is difficult to play the role of regulating and controlling polymer network, hyperbranched content of monomer is excessively high, then monomer polymerization polymerize
Degree reduces, and formation polymer network aperture is excessive, causes the reduction of PSCT scattering strength.
It is further preferred that the hyperbranched monomer is that (manufacturer is the special material in Changxing to ETERCURE 6361-100
Expect Co., Ltd, product grade is ETERCURE 6361-100), pentaerythritol triacrylate (PETA), dipentaerythritol
Amyl-/at least one of hex- acrylic acid (DPHA) and pentaerythritol tetraacrylate (PETTA).
The liquid crystal monomer be 4- (3- acryloxy propoxyl group) benzoic acid 2- methyl-1,4- phenyl ester (RM257) and/
Or bis- [4- (6- acryloxy hexyloxy) the benzoyloxy] -2- methylbenzenes (RM82) of Isosorbide-5-Nitrae -.
Preferably, chiral agent distortion force constant (HTP value) is 30~120.Since liquid crystal screw pitch has been set, HTP
It is worth higher, then the chiral agent content of required addition is lower in liquid crystal compound, and liquid crystal compound physical property is (viscosity, limpid
Point transition temperature etc.) it is smaller by being influenced.
Further, the chiral agent is bis- [4- (trans- -4- pentylcyclohexyl) benzoic acid] (R) -1- phenyl -1,2-
Ethyl (R1011), (13BR) -5,6- dihydro -5- (trans- -4- propylcyclohexyl) -4H- dinaphtho [- H of 2,1-F:1 ', 2 ']
At least one of [1,5] dioxane nonyl tetraene (S5011) and TADDOL class chiral agent.

Preparation method, comprising the following steps:
(1) the liquid crystal compound precursor is prepared；
(2) the liquid crystal compound precursor is poured into liquid crystal cell；
(3) apply alternating current to liquid crystal cell, while carrying out ultraviolet light solidification.
The excessively high liquid crystal that will cause of the ac frequency is difficult to respond, and ac frequency is too low, will cause liquid crystal list
Body vibration causes monomer polymerization to form defect and increases.
The excessively weak monomer that will cause of the ultraviolet light intensity combines not exclusively, and ultraviolet light intensity is too strong that it will cause liquid crystal and monomer
Mutually separation is excessively violent, causes the generation of monomer polymerization defect.
Preferably, the frequency of the alternating current is 1000~25000Hz, and voltage is 80~120V；The light of the ultraviolet light
It is by force 0.2~1mW/cm2。
Compared with prior art, the invention has the benefit that
The present invention, which introduces hyperbranched monomer into liquid crystal compound precursor, can be effectively reduced the response time of liquid crystal light valve,
And the granular sensation phenomenon that liquid crystal light valve occurs in imaging process can be weakened.
