Description
Technical field
The present invention relates to the textile material field, more particularly, relate to a kind of conductive fabric and manufacture method thereof.
Background technology
Because conductive fabric has electric conductivity, elasticity, electrostatic discharge performance, emi protection performance, radio frequency interference protection performance, thermal expansion matching performance and weight characteristic preferably; make it can be widely used in conductive material, textile technology and medical domain, therefore be subjected to extensive concern.Along with the kind of the electronic equipment of installing in the military and commercial aircraft and the increase of complexity, the space that interconnecting cable is required and weight increase together with the demand of the integrality of guaranteeing to send at the higher frequency signal thereupon.
The manufacturing conductive fabric is disclosed in the prior art, as the whole bag of tricks of conductive fiber, silk, cloth and film.As fiber that blending is twined mutually and metal in small, broken bits, silk or the fiber of electrospinning containing metal nano particle, blending conducting polymer, carbon fiber and silk or fiber, or at fiber surface coating conductive material (as metallic particles) and material with carbon element etc.The manufacture method of composite yarn is disclosed respectively as patent application WO93/24689 and EP0644283A.Following manufacture method is disclosed in PCT patent application WO93/24689, the composite yarn that the textile fabric of identical or different type is made and diameter 0.008 and 0.05mm between metal wires such as stiffened, silver-plated or gold-plated copper or annealed steel twist into a bundle, and make described metal wire roughly be positioned at each root textile fabric common contact zone axially on.In US Patent No. 3,987,613 and US 6,032,450 in other weaving techniquess are also disclosed.
These methods are widely used in the manufacturing of conductive fabric, but its defective is do not have continuous metal wire at the length direction along fabric, make that therefore the electric conductivity of whole fabric fibre is also discontinuous.In this case, metal wire keeps extension to a certain degree in conductive fabric, and still, the combination between part fabric fibre and the metal wire is also insufficient tight, therefore the risk that exists fabric fibre to separate with metal wire in subsequent processes.
In the manufacturing of existing conductive fabric, also have the people with the blending of carbon fiber and other material with carbon elements (as graphite, CNT) etc. in conductive fabric.Yet one of important performance of conductive fabric is its ductility, and the elastic modelling quantity of material with carbon element is higher usually, thereby its ductility is often relatively poor.Therefore, in conductive fabric, material with carbon element comes off easily, and fabric fibre ruptures easily.And, compare with similar metal material, adopt the electric conductivity of the conductive fabric that material with carbon element makes relatively poor relatively thereby limited its application at many electricity fields.
For for the conductive fabric of coating conductive material on conductive fiber, can come to form conductive coating at fiber surface by adopting plating and viscose.In electroplating process, cause environmental problem easily, and the adhesion between coating and the substrate merits attention also.
In commercial available also can producing continuously in the method for coat of metal fabric, the fabric that will handle launches from the raw material wheel, through suitable chemical treatment step, then stores take-up pulley into.Unfortunately, in now available textile treatment, the filament that is positioned at fabric is difficult to plate or fully plates metal, and this makes that the coat of metal on the filament is also inhomogeneous.The electric conductivity of the fabric that uneven coating is even is heterogeneity also.In many application, in the application as the protective layer of coaxial cable, the even fabric of uneven coating is unacceptable like this.
Be difficult to by the wet-chemical electroplating method of electroless coating metal evenly and fully is plated in the filament surface of multi-fibre fabric.As U.S. Patent application US 4,522, described in 889, even adopted the electroless coating method to plate the poly-kevlar fabric of pre-braiding of metal (as copper and mickel) for those, fully, fully the coat of metal also is impossible realize, particularly be difficult to produce the infall of the pre-braided fiber of coating usually at those.
U.S. Patent application .5,302,415 and 5,935,706 disclose a kind of method of using the various poly-aramid fibers of electroless plated metalization of copper.This method is used 80 to 90% sulfuric acid modified poly-aramid fiber surface.Can control poly-aramid fiber degraded by the depolymerization of control fiber, and then the sensitizer that deposits for the promotion electroless plated metal provides the deposition site.Consider that based on some the electroless plating structure is not desirable fully.Because adopting wet chemical method directly to deposit to polymer surfaces, previous reasons come deposited copper unsatisfactory.After thermal cycle accelerate to form copper oxide, a little less than the bonding strength of copper layer and fiber surface can become very, finally this will cause the interface in conjunction with inefficacy, and just, the copper layer will show from polymer and come off.In addition, owing to used 80 to 90% sulfuric acid in these patents, it might corrode all natural fabrics, as cotton, silk and cloth.
Therefore, need a kind of can be fully, fully at the natural and surperficial fabric with high conductivity that plates the method for metal and form thus of man-made fabric.

The specific embodiment
Fig. 1 is the schematic flow sheet of conductive fabric manufacture method of the present invention.As shown in Figure 1, in step S1, at first at the fiber surface grafting PMETAC of fabric brush.In one embodiment of the invention, can adopt water mediation surface to cause ATRP to produce poly-[2-(methacrylyl) ethyl-trimethyl ammonium chloride] (PMETAC) grafting from the cotton thread fiber.This water mediation surface starts atom transfer radical polymerization (ATRP) processing can provide higher polymerization speed, and brush thickness, the uniformity and density are carried out preferable control.It is for the synthetic Green Chemistry method of polymer that this ATRP method also is taken as.
In step S2, the fabric of PMETAC being brushed grafting carries out ion-exchange treatment.In one embodiment of the invention, the fabric that the PMETAC of above-mentioned acquisition can be brushed grafting immerses and contains conductive materials, in the aqueous solution as metallic particles, and places a period of time.Because the affinity to the quaternary ammonium group in the fabric of PMETAC grafting of conductive materials is higher, therefore can be by ion-exchange, the PMETAC that conductive materials can be deposited on the grafting of fabric face brushes.
In step S3, the fabric of the brush of the PMETAC after ion-exchange grafting is implemented electroless deposition.In a preferred embodiment of the invention, this fabric can be immersed and contain Cu, Pt, in the metal electroless plating solution of metals such as Au or Ag, thereby at fabric face plated metal particle, thereby obtain conductive fabric of the present invention.
Fig. 2 is the step schematic diagram of second embodiment of conductive fabric manufacture method of the present invention.
As shown in Figure 2, at first with the cotton thread silanization.In a preferred embodiment of the invention, can adopt Br to replace the OH group on cotton thread surface.In other embodiments of the invention, also can adopt other organosilan aqueous solution to handle, those skilled in the art can select as required.
Then, carrying out ATRP handles.In an exemplary embodiments of the present invention, can at first clean the cotton thread surface, subsequently by cotton thread being immersed a period of time in the ATRP initiator solution, and then the ATRP initator is fixed on the cotton thread, carry out subsequent operation again.
In a preferred embodiment of the invention, can be at first cotton thread be immersed in the silica-based propyl group 2 bromo 2 methyl propionic acid of 3-trichlorine that contain 5mM about 10 hours, so that the hydroxyl of cotton thread fiber and silylation generation condensation reaction.Then, use pure dry toluene and washed with dichloromethane cotton thread initiator molecule and the accessory substance molecule to remove excessive physical absorption for several times, then 50 ℃ vacuumize 2 hours.Then the cotton thread that obtains is sealed in the Schlenk pipe logical N
2And 20 ℃ of preservations.
Then can be immersed in the polymeric solution about 10 hours at 60 ℃ of cotton threads that initiator molecule will fixedly be arranged, can generate the PMETAC brush on the cotton thread surface subsequently.In a preferred embodiment of the invention, described polymeric solution can followingly dispose: commercial 9.2g 2-(methacrylyl) ethyl-trimethyl ammonium chloride (METAC) that can buy is dissolved in the 10mLMeOH solution, at 20 ℃ of logical dry N
2, and about 20 minutes of agitating solution.Add the 0.48g dipy subsequently, 0.12g Cu (I) Br and 0.019g Cu (II) Br
2Then lead to and do N
2Stirred this solution 15 minutes.Subsequently this solution is injected in the Schlenk pipe and reacts with cotton thread.
At last, use methyl alcohol with synthetic sample washing for several times, adopt water washing for several times again, subsequently at N
2Middle dry.Use Fourier transform infrared spectrometer to observe subsequently, and verify whether this PMETAC brush grafting process is successful.Fig. 3 is the Fourier transform infrared spectroscopy figure of the cotton thread of grafting PMETAC brush on the cotton thread fiber.As shown in Figure 3, the enhancing peak that causes of the carbonyl of PMETAC is at 1730cm
-1The place; Quaternary ammonium group (QA
+) the new peak value that causes is at 876cm
-1The place.Three different C-H stretching attitudes have caused 2851cm respectively
-1, 2918cm
-1And 2963cm
-1The peak value at place.Fig. 4 is scanning electron microscopy (SEM) figure of cotton thread after the PMETAC graft modification and untreated cotton thread.B among Fig. 4 shows on the surface of undressed cotton thread fiber, and it generally has the gully form less than 50nm, and the surface of the cotton thread after the PMETAC graft modification shown in the C among Fig. 4 is more level and smooth.This level and smooth phenomenon means that the thickness of PMETAC brush is greater than the half-breadth in nanometer gully.Because can't measure the thickness of the PMETAC brush grafting on cotton thread surface, therefore the ATRP contrast experiment who causes by the surface of carrying out on the silicon base surface can estimate that its thickness is about～30nm.Though the actual grafting density that the PMETAC that generates by surperficial initiated polymerization brushes is difficult to accurately record, and it also depends critically upon the performance of monomer, initiator molecule density and the polymerizing condition on cotton thread surface.Yet in fact as long as adopt the PMETAC brush that the cotton thread surface is all covered, accurate grafting density is not very important.It is emphasized that those skilled in the art know, though be that specific embodiment describes in the present invention with the cotton thread, any fabric also can be used for realizing the present invention as man-made fabric such as natural fabrics such as silk, fiber crops, cloth and other terylene.This can be confirmed by SEM figure.
Next can carry out ion-exchange treatment.In one embodiment of the invention, PMETAC can be brushed the cotton thread immersion 5mM (NH of grafting
4)
2PdCl
4About 15 minutes of the aqueous solution (pH～1) is at this PdCl
4 2-Can be fixed to PMETAC by ion-exchange and brush, this is because they are to QA
+Has very high affinity.Wherein palladium is as effective haptoreaction side of the ELD of copper or other metals (for example, gold, silver, platinum etc.).Subsequently, can adopt the cotton thread of proper amount of deionized water washing PMETAC brush grafting.In a preferred embodiment of the invention, adopt the deionized water washing of about 4 * 200mL.
At last, implement electroless deposition.In one embodiment of the invention, the sample after the washing can be immersed a period of time in the electroless plated metal ion deposition liquid.After deposition process finishes, take out samples with water washing and dry.In a preferred embodiment of the invention, described electroless plated metal ion deposition liquid is the copper ion deposit fluid, and it is for comprising 12g/L NaOH, 13g/L CuSO
45H
2The aqueous solution of O, 29g/L potassium sodium tartrate and 9.5mL/L HCHO, and sedimentation time generally is no more than 60 minutes, for example, can select 30 minutes, 60 minutes etc.Can make the conduction cotton thread that Cu NPs of the present invention covers thus.Those skilled in the art know, in other embodiments of the invention, can adopt other electroless plated metal ion deposition liquid that are fit to carry out the metal ion deposition.Known any electroless plated metal ion deposition liquid may be used to the present invention now.
According to instruction of the present invention, those skilled in the art can be used for the present invention the electroless plated metal ion deposition liquid as metals such as gold, silver, platinum.For example, when selected electroless plated metal ion deposition liquid is Ni ion deposition liquid, it is for containing the aqueous solution of 40g/L nickel sulfate hexahydrate compound, 20g/L natrium citricum, 10g/L lactic acid and 1g/L dimethylamine borane (DMAB).Wherein except DMAB, other compositions can mix earlier.The DMAB aqueous solution can dispose separately.Mixed according to 4: 1 then.After mixing, with ammonia pH is adjusted to and is about 8.
The conduction cotton thread that the Cu NPs that obtains according to said method covers have electrical conductance (～1S/cm), and can be used as electric wire.In order to prove this point, we have constructed a simple circuit, adopt the thread electric wire of conductive sponge of the present invention to connect 9V battery and LED lamp.Implement proof, when the Anode and battery anode of LED lamp contacted, the LED lamp was opened at once and is luminous, cuts off connection up to us.
Below our performance of conduction cotton thread that the Cu NPs that makes is covered discuss.In order to verify its performance, we are repeatedly bending, are stretching even washing later electrical stability and detect it.In the present invention, the test of conductance adopts Keithley 2010 universal meters to test according to two probe method.Load (load) and distortion use Instron mechanical test system (model 5566) to record.The distance of test probe is 3.5cm.For furthering repeatedly, sample repeats to reach 50% of maximum distortion when stretching repeatedly and recovering for 30 times.Each 20s consuming time.Each sample test at least five times is averaged.All experiments are all carried out under 20 degrees centigrade and 65%RH.
At first checking is that sedimentation time is that 30 minutes conduction cotton thread is stretching and loosening later electrical stability.At first, we stretch under ad hoc fashion and loosen this conduction cotton thread, and measure its electric conductivity in this stretching with when loosening.We find, what is interesting is, when this conduction cotton thread during by straight stretching (pulling force 2.2N), it demonstrates higher conductance (0.28S/cm), and when pulling force is eliminated, conductance relatively poor (0.04S/cm).And this process remains reversible at 30 times after repeatedly, and the conductance of stretching and relaxation state remains unchanged.Wherein Fig. 5 shows 10 times repeatedly.In Fig. 5, the first half is represented the conductance when the load of its corresponding the latter half.Stretch when conducting electricity cotton thread when bending, and for example twining around pen, its conductance is identical during with its straight stretching.During this situation because when the conduction cotton thread was relaxed, the fiber of composition cotton thread was not in contact with one another, so electrical conductivity is relatively poor.When the conduction cotton thread was stretched, the concentrated more electrical conductivity of therefore conducting electricity cotton thread of fiber wherein increased.At 30 times repeatedly after the experiment, adopt SEM to observe, do not find the copper fault rupture.
Then we adopt detergent wash repeatedly, to detect the durability of conduction cotton thread.In following experiment, we adopt simple hand washing and wring out, and also can carry out especially friction to the conduction cotton thread between this.At last, by N
2Dry up.After 30 cyclic washings and drying, do not find the obvious variation of its conductance.Adopt SEM also not observe the appearance fracture of copper coating.Should be noted in the discussion above that in traditional industry bonding between metal and the basic unit is a main difficult problem.The metal level that directly is plated on cotton thread/fiber tends to come off after bending or friction, more is difficult to stand washing test.Therefore, conductive fabric of the present invention obviously is better than the conductive fabric that prior art makes.The method of manufacturing conductive fabric of the present invention also obviously is better than the method for available technology adopting.
Find by studying us, can control the electrical conductivity of conductive fabric by the control electroless plating time.Fig. 7 is conductive fiber weight and concerns schematic diagram between the electroless plating time.As shown in Figure 7, the electroless plating time is more long, and the metal of deposition is more many, and conductive fiber weight is more heavy, and conductance is also just more high.Yet when the electroless plating time reached 60 minutes, the metal deposition reached capacity.As shown in Figure 7, in that being immersed in, the cotton thread after the PMETAC graft modification comprises 12g/L NaOH, 13g/L CuSO
45H
2After 60 minutes, the weight of cotton thread increases by 2 times in the electroless plated metal ion deposition liquid of O, 29g/L potassium sodium tartrate and 9.5mL/L HCHO.Fig. 8 is the SEM figure with the conduction cotton thread of the formation of the cotton thread electroless deposition different time after the PMETAC graft modification.Wherein A is immersed in the cotton thread after the PMETAC graft modification to comprise 12g/LNaOH, 13g/L CuSO
45H
2The SEM figure of the cotton thread that forms 0 minute the time in the electroless plated metal ion deposition liquid of O, 29g/L potassium sodium tartrate and 9.5mL/L HCHO, the SEM figure of the cotton thread that forms when B is 1 minute, the SEM figure of the cotton thread that forms when C is 10 minutes; The SEM figure of the cotton thread that forms when D is 30 minutes.As B among Fig. 8 as seen, in the time of 1 minute, the copper particle that diameter is about 130 ± 20nm begins to deposit on the cotton thread.As D among Fig. 8 as seen, after 30 minutes deposition, the thickness of copper layer is greater than 1 μ m.
In order to study better, adopt energy-dispersive spectroscopy instrument (EDX) to observe the ELD reaction.Fig. 9 is the EDX figure with the conduction cotton thread of the formation of the cotton thread electroless deposition different time after the PMETAC graft modification.Wherein A is the EDX figure of electroless deposition in the time of 5 seconds, and B is the EDX figure of electroless deposition in the time of 10 minutes.Shown in A, when electroless deposition in the time of 5 seconds, only cotton thread blackening, EDX only detects palladium, and only can observe the copper signal of trace.As time goes by, cotton thread expands gradually.The Cu NPs that diameter is about 130 ± 20nm begins to deposit on the cotton thread.The size of NPs does not significantly change, and the thickness of copper layer increases.After 30 minutes deposition, the thickness of copper layer is greater than 1 μ m.When the electroless plating time reached 60 minutes, the metal deposition reached capacity, and the weight of cotton thread increases by 2 times.In control experiment, as fixing PdCl not
4 2, will can not observe Cu NPs.
Certainly, we also can be to intensity and the extension performance of the conduction cotton thread that obtains.Fracture strength and the extensibility of the conduction cotton thread of copper plate are respectively 6.4N and 9.1%, and be only small in unmodified cotton thread (7.2N and 10%).And only be respectively 5.8N and 8.3% by fracture strength and the extensibility of the cotton thread of initator modification.The cotton hierarchy of copper of this explanation PMETAC grafting can be fiber provides extra intensity and ductility.
Because when being placed on cotton thread in the air, eremacausis may take place Cu NPs and conductance descends.Therefore, in a preferred embodiment of the invention, but other metal nanoparticles stable in the air come Alloy instead of Copper, for example can select Ni, come based on the method for preparing conductive fabric.When method of the present invention was used for Ni, those skilled in the art can select suitable reagent and electroless plating time as required.Figure 11 shows the SEM figure of the conduction cotton thread that uses the Ni preparation.Figure 12 shows the SEM figure that PMETAC brush is put into behind the Ni electroless plating liquid 2 hours the conduction cotton thread that makes.Figure 13 shows the conductivity test figure of the conduction cotton thread of Ni preparation.
Those skilled in the art knows that the conductive fabric of the present invention's preparation can also be widely used in other field except being used for electric wire, such as being used as functional infrared external reflection thing.As conductive fiber that copper nano particles coating has been shown among Figure 14 thermo-effect of infrared radiation with the IR irradiation time.
Though the present invention describes by specific embodiment, it will be appreciated by those skilled in the art that, without departing from the present invention, can also carry out various conversion and be equal to alternative the present invention.Therefore, the present invention is not limited to disclosed specific embodiment, and should comprise the whole embodiments that fall in the claim scope of the present invention.
