Description
Technical field
The utility model belongs to color-changing anti-counterfeit label technique field, is specifically related to a kind of based on electrochromic antifalsification label.
Background technology
At present; Existing antifalsification label mainly is divided into five big types of laser scanning label, query formulation digital label, pattern texture label, safety line cheque paper label and wireless electron scanning antifalsification labels, has mainly utilized the characteristic of aspects such as optics that material itself has, calorifics.The consumer is through visual inspection, interactive query or produce by professional instrument detecting label with normality under different variations distinguish that product is true and false.But counterfeit technology of today is increasingly high, and the technological means that the part antifalsification label is used is single; With low content of technology; Causing can the raising of counterfeit property, the reduction of label anti-counterfeit property, a lot of in addition antifalsification labels or need distinguish by instrumentation; Or the label variations effect is complicated, thereby brings bigger difficulty for consumer's identification.In addition, for solve make complicated, problem such as operation is many, somebody (CN2487062) utilization nano semiconductor material is made the electrochromism anti-counterfeiting mark.Though having solved to a certain extent, this electrochromism anti-counterfeiting mark makes complicacy; Problems such as operation is many; But the used nano semiconductor material cost of this anti-counterfeiting mark is expensive, and the security devices that forms still has seven-layer structure, and design is comparatively complicated; Production process is still more, causes production cost higher.
Summary of the invention
The utility model provides a kind of electrochromism antifalsification label that electrochemical properties designed new, that utilize material to the problem that prior art exists.
The electrochromism antifalsification label that the utility model provides; This label comprises surperficial anode layer, surperficial cathode layer, electrochromic material layer and the lead of the external power supply of being drawn by surperficial anode layer, surperficial cathode layer; It is characterized in that also being provided with an electrolyte conductive layer between surperficial anode layer and the electrochromic material layer, wherein the antifalsification label pattern is positioned at the electrochromic material layer.
The inside surface that the surperficial anode layer of above-mentioned label contacts with the electrochromic material layer, surperficial cathode layer are coated with nesa coating with the inside surface that the electrolyte conductive layer contacts.
Wherein surperficial anode layer is to be made up of transparency higher organic polymer film or optical clear glass.The electrochromic material layer can be by inorganic material such as tungstic acid, titania, perhaps adopts methods such as general chemistry is synthesized, electrochemical deposition, sol-gel process to prepare by materials such as organic material such as polyaniline and derivant thereof, smart class of purple sieve, polythiophenes.The color changeable effect and change variable color voltage range of other materials to obtain enriching can also mix in electrochromic material; And the antifalsification label pattern is that query formulation digital label, texture label, word tag can be made the picture and text template; Through the method for etching or coating, make the vestige of corresponding pattern at this layer.This vestige is the water white transparency state because of material itself and surperficial anode and cathode layer and electrolyte conductive layer under common state, do not see the picture and text of inside through naked eyes.But after adding certain voltage, electrochromic material layer change color can show picture and text.The consumer can be according to the picture and text that show, contrast standard collection of illustrative plates or online inquiry bar code wait distinguishes authenticity of products.Can in the certain voltage scope, realize the reversible variation of color because the raw material that the utility model electrochromic material layer is adopted has, but reduce the characteristic that its color of voltage no longer changes behind the magnitude of voltage that oversteps the extreme limit again.For avoiding antifalsification label to be lost antifalse effect by second use, the supply voltage during this searching label should be the limiting voltage of material, in case after its variable color was shown, color relation no longer reversed.The electrolyte conductive layer is by lithium perchlorate solution, potassium chloride-salpeter solution or solid electrolyte material such as LiClO
4The gel rubber system that-PMMA-PC constitutes, TBAP-PMMA-PC gel rubber system constitute.The electrolyte conductive layer is liquid in this way, can be encapsulated in the cavity of electrochromic material layer and surperficial cathode layer formation.The surface cathode layer is to be made up of transparency higher organic polymer film or optical clear glass.The external power supply wire that surface anode layer, surperficial cathode layer are drawn is respectively as the positive and negative electrode external power supply.The nesa coating that inside surface, surperficial cathode layer that the surface anode layer contacts with the electrochromic material layer and the inside surface that the electrolyte conductive layer contacts all apply is indium tin oxide conductive film or zinc paste-aluminium conducting film or tin oxide-titanium dioxide conducting film.External power supply can be the power supply that exchange to change direct current, the direct supply that also can provide by dry cell, silver-colored core battery etc., and can cooperate rheostat to change magnitude of voltage, but also can constant voltage directly supply power.Be to improve antifalse effect, the dedicated variable voltage power supply device of source resistance that can also be the special packaged combination of making as required.
The utility model is the electrochromism antifalsification label that each layer combined closely and formed with the as a whole back of epoxy encapsulation, and this antifalsification label can directly be attached to be needed on the false proof product surface.It is the water white transparency state that outward appearance is observed label, as long as the label additional power source is switched on, can manifest predetermined picture and text when the consumer discerns.
The utility model compared with prior art has the following advantages:
1, because the cross-section structure of the utility model is four layers; And what utilize is that the electrochemical properties of material designs thereby not only simple in structure, production process greatly reduces; Production cost greatly reduces, and has avoided making the problem that the electrochromism anti-counterfeiting mark is brought with nano semiconductor material.
2, because the utility model is the electrochemical properties of the material that utilizes designs, thereby anti-counterfeit recognition is convenient and swift, and this identifying is irreversible in addition, can also avoid being lost antifalse effect by second use.
