The length and width of " w " and composite construction is more much bigger than its thickness " t ".Preferably, the thickness that dielectric layer is had is from about
In the range of 10 μm to about 100 μm, wherein the gross thickness of structure is in the range of about 15 μm to about 10cm.Additionally, it is desirable to
Select elastic modelling quantity, thickness and/or the geometry of electrode 14,16, lead to so that they contribute to the additional hardness of actuator
The often less than hardness of dielectric layer 12, described dielectric layer 12 has relatively low elastic modelling quantity and (is i.e. less than about 100MPa and more excellent
Selection of land is less than about 10MPa) it is likely that thicker than each in electrode.Be suitable to comply with capacitive structure with these be used together
Electrode be can stand greater than about 1% cyclic strain and those electrodes of not breaking down because of mechanical fatigue.
As see in Figure 1B, when a voltage is applied across the electrodes, the charges of different polarity in two electrodes 14,16 are each other
Attract, and these electrostatic attractions force compresses dielectric film 12(is along Z axis).So that this dielectric film 12 with electric field change and

In, electroactive polymer membrane 26 includes (such as by acrylate, silicones, urethane, thermoplastic elastomer (TPE), hydrocarbon rubbers, fluorine rubber
Glue, copolymer elastomer etc. are made) thin layer of elastomeric dielectric polymer.Electricity when the opposite charges crossing over each work pair
Pole 32(i.e., cross over film 26 either side on paired electrode) apply voltage difference time, opposite electrode attracts one another, and thus compresses it
Dielectric polymer layer 26 between.Region between opposite electrode is counted as active region.Along with electrode is pulled more to lean on
The most together, dielectric polymer 26 becomes thinner (i.e. z-component contraction), because it expands (i.e. X-axis and Y in the in-plane direction
Axle component expands) (for axle reference, see Figure 1B).Additionally, in the electrode package deformation containing conductive particle, be distributed in each electricity
The same sex electric charge extremely gone up may make the conductive particle being embedded in this electrode repel each other, thus to elastic electrode and dielectric film
Expansion contributes.In replaceable deformation, electrode does not comprise conductive particle (such as reticulate pattern sputtering metal membrane).So that be situated between
Electric layer 26 deflects with the change of electric field.Because electrode material is also compliance, electrode layer changes shape with dielectric layer 26

(that is, biaxial stretcher).Desired stretching will depend upon which expected performance and the application of electroactive polymer device.Such as, may be used
Material is stretched 30% in any one in machine direction and horizontal direction or both.
In some cases, it may be desirable that the supporting layer to film 96 is provided after the stretch.If it were to be so, it is permissible
Laminate layers 308 is added film 96 to provide the additional support being used for the process to film.As discussed below, lamination
308 are also used for reducing the incidence rate of fracture in film 96 and damaged area being limited to the non-critical section of film 96.This laminate layers

To the skew caused by the opening in break-resistance layer, to adjust typography, (such as, printing spool may make axle sleeve raise, should
Axle sleeve is aligned the time and is not laminated part be printed on film 96).Additionally, the registration of film 96 roll position is probably and guarantees electricity
In pole is printed on the opening of break-resistance lamination and necessary on the reel of film 96.Can be by printing or similar application
Conventional any such registration application is in technique disclosed herein.
Fig. 3 A also illustrates the printing carried out on two surfaces of film 96.As indicated above, at film 96
Electrode is needed to place on every side.In the replaceable deformation of this technique, can print on the single side of film 96, so
After, this film 96 is wound around and is utilized the printing carried out on the opposite sides to be reprocessed in subsequent technique again.Alternatively, single
The film of side printing can be stacked or be laminated, and the most single electrode can be used to provide two adjacent membranes in multiple-level stack
Service.Under any circumstance, registration is probably and guarantees electrode print on the opposite side of membrane material and the different sections of film
On be within manufacturing tolerance necessary.
Once electrode is placed on film 96, it is possible to utilize the insertion between each layer of film 96 or stratum disjunctum 314
This film 96 is wound around again.Alternatively, film 96 can continue additional treatments to assemble electroactive gathering as described here
Compound framework and supporting construction.
Fig. 3 B illustrates, in the technique producing double-layer electric living polymer device, printing elastica 96 material is entered one
The example that step processes.It is shown that the two of print film 96 sources can be fed 316 or be wound around and engage to be formed double again

Property polymer device (such as cross cutting, punching, cut etc.).Clearly, the deformation of technique can be included in appointing of technique
Remove material after what in stage, therefore, it can in batch processing rather than in transfer tape assemble system, complete this device.This
Outward, the deformation of technique includes being wound around the electroactive polymer device completed again removing for follow-up.
In replaceable deformation, the technique for making electroactive polymer device can include elastomeric polymer UV,
Heat or surface process.Lead it has been found by the inventor that this film is carried out UV process before by electrode deposition on film
The improvement stroke performance of the actuator caused.While not wishing to be bound in any particular theory, but the invention of the present invention
People believes, UV exposure, silicones, polyurethane, acrylate, hydrocarbon rubbers, olefin copolymer, polyvinylidene fluoride copolymers thing, fluorine
Rubber, styrol copolymer and adhesive elastomer may change the uniformity that the surface energy of film deposits with modified electrode.Additionally,
The present inventor speculates, UV solidification may change bulk modulus or other attributes of elastomer, so that it better conforms to, and
And UV process can revise in a manufacturing process heat load during crosslinking polymeric film in remaining function group.
No matter actual mechanism how, it has been found by the inventor that UV solidification is the stroke for improving actuator
Effective process of performance.In one example, compared with non-UV curing elastomer, UV solidification makes the impulse response of actuator improve
20% and characterize actuator with more low resonant frequency.The parameter of UV solidification is by the expectation according to final electroactive polymer device
Application and many factors and change.In one example, it was found that 6.5-7.0 J/cm2UV solidification be to improve the rushing of actuator
The optimum point that the UV of Cheng Xingneng processes.UV solidification (before depositing electrode) another unexpected advantage be: UV solidification and
Queuing time between electrode print is not sensible factor.In the research carried out by the present inventor, queuing time can
To last up to 25 days.This result of study may potentially allow for carrying out immediately UV solidification during or after making film prestrain.
In some cases, operations described below can be possible: processes elastomer during film manufactures, so that being made into from elastica
Time keep these advantages to when processing as described herein this film.
By volume to volume manufacture, one of problem being used for elastica (such as silicones) is: relatively thin (such as 23 μ of film in trial
M), there is low-down modulus simultaneously.In the case of not applying prestrain, responsive membrane can not keep smooth, but simultaneously, film
May easily tear or rupture.Meeting high actuator performance additionally, be manufactured in order to ensure device, film is in printing and lamination phase
Between need high level apply strain.In the case of framework does not keeps and maintains prestrain, the electrode figure being printed on film
Case has registration and the possible poor relatively high likelihood of deformation of printed patterns.If film deforms during printing operation, then may be used
So that this film is inoperative for the use in electroactive polymer actuator.
In order to solve this problem, the deformation of manufacturing process of the present invention includes single shaft prestrain is put on electroactive polymer
Film.Experiment has shown that under certain conditions, and uniaxial strain can match with the stroke performance of rule twin shaft prestrain film.
Identical with the twin shaft prestrain after stretching, single shaft prestrain value can be limited by the index of thickness.Such as, single
Axial strain (on thickness direction, 67% strains with on XY direction 0%) can have similar with biaxial strain (in both direction 30%)
Film thickness scope.Longer output bars direction is parallel with single shaft prestrain direction.
In order to realize single shaft prestrain in volume to volume system, it is possible to use perforated strip as shown in Figure 4A and 4B
360 two edges keeping elastica 96 on reel (longitudinally) direction.Can be by stretching this film in a lateral direction
Apply uniaxial strain, and on reel direction, there is zero prestrain or low prestrain.The output bars of electroactive polymer box is permissible
It is designed to vertical with reel direction.One deformation of this technique uses while being included in the degree of controlled strain and direction and wears
Hole (or sprocket wheel or pin type feed) spool keeps ribbon and film (seeing Fig. 4 C and 4D).
Can be accurately controlled the horizontal and vertical position of ribbon 360 by perforation spool, therefore, local train will
It is consistent and stable.This allows multiple printings as described herein and curing schedule.By two long edges of elastica 96
On two ribbons 360 between distance limit principal strain.
Ribbon 360 can be constructed by than the material of elastica much harder.Such as, ribbon 360 can include poly-right
PET, it has the Young's modulus between 2800-3100MPa, and tensile strength is 55-75MPa.Compare it
Under, silicones (common materials of elastica) has the Young's modulus of 1-5MPa, and tensile strength is 5-8MPa.Correspondingly, poly-
Ethylene glycol terephthalate be about 1000 times of silicone resin film hard.
When applying tension force by spool 362, major part power will be applied to that polyethylene terephthalate banding
Thing 360 rather than film 96.For example, it is assumed that there is the prolongation of 5% on reel, then 400 in 401 parts of power are applied to gather
On ethylene glycol terephthalate ribbon, and 1 part is applied on silicone resin film (assume polyethylene terephthalate
Ester is 50 μ m-thick and 25mm width;And silicone resin film is 25 μ m-thick and 500mm width).This avoids and directly uses on silicone resin film
Tension force spool is to control the needs of the strain of film.If employing tension force spool, then be applied in silicone resin film tension force appoint
The big change what little change will cause film to extend, this will be difficult to control to.
If ribbon is made up of Stretch material or is segmented (such as utilizing perforation line), then can utilize perforated tape
Shape thing completes biaxial stretch-formed, and therefore, when stretching along reel direction, the section of ribbon can separate, and remains along simultaneously
The edge of reel engages with perforation spool or guide chain.
