The device that rugosity is regulated and controled has various potential applications, such as response elastomer is exactly the material for having this potential application
Material, and liquid crystal polymer needs to cause modification of surface morphology by stimulating as a kind of special response elastomer（For example,
S order parameter by reducing molecules align is realized）.For different stimulations, there is many research at present, for example, temperature, illumination,
Chemical stimulation etc., the above stimulation mode reduce the S order parameter of single domain liquid crystal film by different working mechanisms.There is research in the recent period
It has been shown that, current potential can also stimulate liquid crystal film and the pattern on farmland to change.For example, electric field can cause subtracting for S order parameter in liquid crystal cells
It is few, cause the generation of free volume, while with generation relative to the contraction in material array direction and the deformation of expanded form.Example
Such as existing research indicates in the face of liquid crystal film/electrode of side arrangement on the generation AC voltages that apply to generate electric field.When
When alternating electric field is matched with liquid crystal network eigenfrequency, resonance effect can be caused, and promote the generation of free volume and deformation.

Thickness in about 6% tunes,（2）It needs just cause apparent pattern to change higher than the AC voltages of 600kHz to 1MhZ,（3）It hangs down
The section that straight becomes is limited to the section of lower electrodes;（4）There is sharp peak value, side to decline rapidly for vertical deformation, no
Platform pattern can be formed;（5）The extension of VERTICAL DEFORMATION depends on transverse electrode and arranges and its be spaced,（6）It needs single domain LC films
Liquid crystal cells arrange the additional preparation steps of polymerization in advance.
With regard to the competitive aspect of material system：So far, the isotropism multidomain nematic between being clipped in perforated electrodes
Change in topology is not yet observed in type elastomer.It is much like in other LC systems and non-LC dielectric elastomers, all lay particular emphasis on
Design to actuator.For non-LC systems, the modulation constrained physical principle in Maxwell effect.Nearest research is base
In obtaining the basic physical property with optimization, such as Young's modulus E relative quiescent permittivity εsrWith the material of breakdown voltage U/d
To improve modulation/strain.However, the effect of material is still limited by the physical principle of Maxwell effect.

Specific implementation mode
Further illustrated the present invention below in conjunction with specific embodiments and the drawings, but embodiment the present invention is not done it is any
The restriction of form.Unless stated otherwise, the present invention uses reagent, method and apparatus is the art conventional reagent, methods
And equipment.
Unless stated otherwise, agents useful for same and material of the present invention are purchased in market.
Embodiment 1
The changeable surface topography on the surfaces LC is realized by the electric field perpendicular to membrane plane, wherein top electrodes are conductive metals
Network.
The system is combined into a device by three individual components：（1）Continuous bottom electrode,（2）As top electricity
The perforation conductive network of pole, and（3）It is clipped in（1）With（2）Between the liquid crystal elastic body of sandwich-like that constitutes.
1, continuous bottom electrode：
By physical vapour deposition (PVD) continuous bottom electrode is made in the silver of deposition on glass 300nm thickness.Before depositing Ag,
Need adherency of the adhesive phase of the Cr of deposition 5nm thickness to improve glass to Ag.But continuous bottom electrode is not limited to these materials
Material.Substantially, any continuous conduction material with flat surfaces and low surface roughness can be used.For example, metal, carbon is same
Plain obform body, transparent conductive oxide and other conductive materials can be deposited as film on a planar substrate.In addition, polishing
Conductive block materials and thin slice may also be used as this material.
2, perforated top electrode：
Top electrodes are used as using self-forming metalolic network.Electrode can be described as the metalolic network being coupled to each other or perforation
Metallic film.It is the photoetching making on glass slide, and compared with other transparent metal conductors, has excellent conductance
Rate and transmissivity, wherein transmissivity are that the score of perforation field directly obtains.Lithographic template can be by drying in gel film
Crackle is formed in the process to obtain.Egg white and nail polish are the gels for being typically available to this purpose.It is solidifying to usually require spin coating application
Glue.However, other technologies can also be used, including other skills such as the dispersion of dip coated or liquid in the spacer of limited bulk
Art.Then, by metal（It is Ag in our case）It is deposited on by physical vapour deposition (PVD) and passes through the crack in template.When
Other metal deposition techniques can also so be used.For example, having recently been developed and full liquid technology as this method class.I.e.
Removing template is removed with organic solvent and distilled water, the metalolic network of interconnection is generated on glass, it appears that is crackle template
Negative-appearing image.
Any discontinuous conductive material can be used in principle（Mean to can not be film, but there is trepanning knot
The network of structure）.Other than the scramble network that we use, it can also use and rule is prepared based on photoetching or self-assembling technique
With irregular metal network.
3, liquid crystal elastic body
With " 4- cyanophenols 4-（6- acryloxy hexyloxies）Benzoic ether " is used as monomer, 2% diacrylate crosslinking agents
" 1- hydroxycyclohexylphenyls are as UV photoinitiators with 2%.The mixture does not have liquid crystalline phase initially, but passes through polymerization
Afterwards, nematic phase is can get in prodigious temperature range.When mixture polymerize in isotropic phase and is crosslinked simultaneously, finally
Obtained material have it is smaller, be difficult to define multidomain structure.This is considered as a kind of nematic network of the isotropism origin cause of formation, with
The nematic traditional material polymerizeing at 90 DEG C is compared, and has the characteristic for needing low-force quantitative change shape.The base of liquid crystal elastic body
This requirement is that it is isotropism multidomain nematic crystal elastomer.Ideally, in order to can make to gather at a lower temperature
It closes reaction in correct phase to occur, it usually needs use the lower similar LC elastomers of glass transition temperature.Material it is soft
Softness is the relevant parameter with our device optimization, monomer, the selection of crosslinking agent and photoinitiator molecules and they
Concentration can all influence the modulation of material softness degree.
The production process and concrete operations flow of device are seen figure 1 and figure 2, the uniform floor on glass well prepared in advance
Electrode（Fig. 2 a）With perforated top electrode（Fig. 2 b）.Then two electrodes faces are arranged, and is separated by particle spacer.Directly
The spacer that 3 μm to 100 μm of diameter be normally based on silica but it is also possible to be based on polymer.Liquid crystal compound quilt
In the free volume of filling between the electrodes, thickness is determined by spacer diameter.At 90 DEG C, liquid crystal compound be in it is each to
In same sex phase.5-10 minutes are irradiated to start polymerisation by UV（Fig. 2 c）.Finally, the glass slide for removing perforated electrodes, is stayed
Lower perforated metal electrode, and it is embedded into isotropism multidomain nematic crystal surface of elastomer（Fig. 2 d）.
Operating principle is as shown in Figure 3.Get out state as shown in Figure 3a, at the same in the case of no application current potential at
In closed state.When applying DC potentials, perforated electrodes are drawn into LC elastomers, cause the perforation exposed from top electrodes prominent
It rises.It is opening state shown in Fig. 3 b.Both states are reversible switchings, and can be adjusted by the voltage of application logical
The height of electricity condition protrusion.
The three-D profile of these states is as shown in Figure 4.Shown data are to be collected with optical profilometer, and can show
Its pattern.Difference in height is indicated using the color range of display.Closed state is shown in fig.4.There is no apparent difference in height
It is different as it can be seen that but it will be apparent that ground distinguish perforated electrodes solid conductor.Fig. 4 b and Fig. 4 c respectively illustrate apply 150V and
Two kinds of conducting states of 250V voltages.It is obvious that the apparent pattern variation of the platform-like projecting manner occurred from perforation.
By calculating, it is 250V that we, which realize applying voltage, when film thickness is 9 μm, obtains up to 1 μm of protrusion, right
It should be in 11% modulation.It is expected that the extension of Maxwell effect can be approximated to be the region for being assumed to be electric wire and following uniform electricity
Pole forms plane-parallel capacitor together.Use above formula and experiment determining Y=1.65MPa and e εr=1.92, calculating
Theoretical value corresponds to the only difference in height of 70nm of 0.8% modulation.The film of 9 μ m-thicks and 27.8V/ μm of electric-field strength for shown in
The value of degree, the device actual test made in of the invention is bigger than theoretical calculation, 9 μm=900nm, is 70nm in theoretical calculation, surpasses
Go out more than 10 times, breached the limitation of Maxwell effect, has fabulous application prospect.
