Technical field
The present invention relates to a kind of preparation methods of light modulation device more particularly to a kind of prepared using nucleocapsid tack microballon to adjust
The method of optical device.
Background of invention
Light modulation device is a kind of photoelectric device adjusting its light transmittance, mist degree, color etc. by voltage driving.It can apply
The fields such as high-end external wall, intelligent automobile glass, office space or even space flight and aviation, have broad application prospects.In recent years
Come, the development of electrochromism technology is increasingly mature, just gradually moves towards industrialization.If Boeing is by electrochromism technology application
In on 787 passenger aircraft cabin glass of Boeing.
The usually for example same sandwich of entire light modulation device structure, by the light modulation of two transparent conductive substrates and intermediate clamping
System layer is constituted.Wherein transparent conductive substrate can be the ito glass plate of hard, can also be the soft of similar transparent conductive film
Membrane material；And it can be solid material, semisolid and liquid material to dim system layer.
When assembling light modulation device, typically use the substance of adhesive class by two pieces in electrically-conductive backing plate edge
Substrate bonding gets up, this but makes the centre of entire device be in a kind of nothing（Adhesive）The state of support, so that just at last
The hard substrates such as glass can also form the high etat lacunaire of intermediate low surrounding.This recess can become because of the increase of device size
Must be particularly evident, seriously affect the uniformity of device, aesthetics even can cause short circuit to make component failure because two electrodes contact.
It is just reaching its maturity to the research of flexible and transparent conductive material at present, flexibility light modulation product will also become a kind of trend.Flexible base
Material undoubtedly more needs to solve the problems, such as unsupported.
Problem is collapsed for this, the solution taken at present is that glass microballoon is placed between two substrates, to play one
Fixed supporting role.But since glass microballoon is not fixed wherein and is also easily slided in itself, cause to sprawl uneven, support effect
Fruit is unsatisfactory.
Light modulation device just must be by dimension enlargement, and before making large-size device to play value in fields such as buildings
First what is carried is to solve the problems, such as to collapse.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of sides preparing light modulation device using the tack microballon of nucleocapsid
Method, this method can collapse problem with effective solution light modulation device.
The present invention provides a kind of method preparing light modulation device using nucleocapsid tack microballon, which includes following

Preferably, the sticky material includes：Heat-sensitive glue, light-sensitive emulsion, pressure sensitive adhesive, hot melt adhesive, light binding or combinations thereof.
The preparation method of the tack nucleocapsid microballon, it is characterised in that include the following steps：
Step 1：It takes the appropriate cohesive material for preparing shell to be dissolved in volatile solvent, the solution with certain viscosity is made；
Step 2：Ball prepared by rigid is placed in the solution and is stirred, keeps ball surface attachment last layer very thin
Cohesive material, microballon is filtered out using gauze later；
Step 3：After the volatile ingredient of bead surface is evaporated completely, microballon is placed in mortar, is lightly ground, will be sticky in
Microballon together is peeled away, and tack nucleocapsid microballon is obtained.
Invention further provides the light modulation systems between a kind of light modulation device, including two panels transparent electrode and electrode
Layer, it is characterised in that nucleocapsid microballon is bonded between the two panels transparent electrode, the nucleocapsid microballon is by ball and package ball
Shell composition, the ball is rigid, and the shell is sticky material.
It is an advantage of the current invention that the isolation Supporting Media being clipped between two electrode plates is that a kind of viscosity of nucleocapsid is micro-
Pearl.Sticky shell can be such that microballon is sticked on two electrodes, play the role of it is fixed, avoid microballon because tilt etc. factors lead to one
Side, which assembles to be formed, to be unevenly distributed, and electrode plate is caused to be unable to uniform stressed；The core of hard will not occur under weight simultaneously
Deformation has thus ensured that microballon can play support buffer action always, has ensured interelectrode interval, device is avoided locally to collapse
It falls into and short-circuit.

Specific implementation mode：
To further understand the present invention, specific implementation mode is described below in conjunction with the accompanying drawings, it should be understood that these descriptions are only
It is to better illustrate the feature and a little of the present invention, is not limiting to the claimed invention.
The present invention provides a kind of method that the tack microballon using nucleocapsid prepares light modulation device, the systems of this method
It is standby that steps are as follows（Referring to Fig. 1 and Fig. 2）：
（1）In a piece of transparent electrode plate（First transparency electrode）The edge coating binder of conducting surface（Electrode side outer rim
Slightly reserving some facilitates connection power supply more）, and gap at reserved two；
（2）Nucleocapsid microballon is evenly arranged on first transparency electrode plate, and by the second plate electrode（Second transparency electrode）Lead
Electric face dislocation fitting is on the first electrode；
（3）It is handled by heat treatment/any mode of photo-irradiation treatment/pressure treatment or combinations thereof so that the shell of nucleocapsid microballon
Viscosity is formed, two electrodes are bonded together to form equidistant cavity, nucleocapsid microballon is fixed, and does not form sliding under external force；
（4）Electrochromic solutions are uniformly injected into the cavity between two electrodes by gap, will be slitted with fluid sealant after being full of
Mouth sealing；
