Description
Technical field
The present invention relates to a kind of color-changing camouflage fabric based on transmission type electrochromic device and preparation method thereof, the electrochromism high polymer that soon under different low-voltages, presents different colours, and solid-state electrolyte layer and ion storage be placed between top transparent electrode and the layer fabric electrode, color-changing camouflage fabric that the electrolyte by glue effectively connects levels and preparation method thereof.
Background technology
The camouflage fabric camouflage.Camouflage fatigue is blended in background by polychrome piece reasonably combined destruction overall profile feature and with integral color, makes the spectral reflectivity of camouflage fatigue similar to background, thereby reaches camouflage effectiveness.Because the atural object and the vegetation condition of various operational environments vary, so produced respectively pattern or camouflage fatigues such as jungle, forest land, desert, ocean, city and mountain region, plateau, polar region and snowfield camouflage color with each adaptive environment facies fusion.Obviously, the forest land camouflage color can not obtain merging in the desert background, and the jungle camouflage color also can not obtain good hidden effect on snowfield.Therefore, the researcher of the military pays close attention to the color-changing camouflage pattern or the clothes that can all can reach good camouflage effectiveness under two kinds even multiple environment always.
As a kind of desirable fighting uniform camouflage protective fabric, color-changing camouflage is subjected to the positive regard of army of developed country always, and U.S. army and Japanese army have just begun the research of color-changing camouflage from the sixties.The track of its exploitation is as follows: the variable color notion and the target that at first propose " chameleon " fighting uniform, the i.e. typical discoloration effect of " soldier is shown in red on red carpet, run into attack when hiding in grove shown in green ", but shortage possibility with regard to science and technology at that time in fact, and there is not military value yet; Then in conjunction with the scientific and technical research of off-color material, luminescent material and flexible display, be divided into two kinds of technology paths gradually, that is:
(1) having got rid of what be difficult to realize ACTIVE CONTROL is the off-color material of inducement with factors such as heat, light, wet, pressure, be devoted to the particularly research of conducting polymer composite and transition metal oxide electrochromic material of electrochromic material, and wish electroluminescent material also is applied to color-changing camouflage.But the still difficult specification requirement of satisfying color-changing camouflage of form and aspect, driving voltage stability requirement, variable color response speed and possibility of reversal number of times before and after the electrochromic material variable color, the camouflage effectiveness of electroluminescent material is also undesirable.So also do not show its color-changing camouflage sample at present,, do not have the relevant report on the scientific and technical meaning at present yet because of the confidentiality of military scientific research based on electrochromism and electroluminescent material;
(2) adopt the mode that background image extracts and the clothes direct picture shows, promptly form clothing system with microcam and Organic Light Emitting Diode flexible display material such as (OLED), background image is imaged in the clothes front, top view person is lumped together image on the clothes and background, reach camouflage effectiveness.This mode can adapt to the diversity of settings condition, and still: A. adopts OLED illumination mode itself just to be unfavorable for hidden easy exposure; B. clothes can only show a kind of image, so can only pretend very easy exposure when changing an angle observation to a direction; C. system is huge, loses actual military significance.Tokyo Univ Japan has this type of " suitable scape camouflage " to study and has sample to show at present.
Though often have report foreign military (even) succeed in developing color-changing camouflage with similar lizard (chameleon) discoloration effect, with temperature, humidity, pH value change, the off-color material of physical chemical factor is changed to inducement such as illumination excites, electric field excites also occurred, but can the controlled circulation variable color and do not see open report with the color-changing camouflage that two kinds and above different landforms visual signature match respectively.
The electrochromic device technology.Electrochromism (EC) is meant material under the electric field or the function of current, light absorption or light scattering takes place cause color that the phenomenon of reversible variation takes place.Electrochromic material with practical value has low switching voltage, is generally-1V～1V; Good intrinsic memory effect and variable color efficient, cycle period and cyclical stability.Comprise organic and inorganic electrochromic two big class materials, common electrochromic material has WO
3, transition metal oxide such as TiO2, the blue series of organic matter and Prussia such as conducting polymer, the phthalein flower mountain valley with clumps of trees and bamboo, liquid crystal.Wherein, the inorganic electrochromic thing is used widely industrial, such as WO
3Be used for electrochromic, but the shortcoming of inorganic electrochromic thing is that complicated process of preparation, cost height and glow color difficulty are regulated, color category is less and be difficult to realize flexibility.The process of organic conductive macromolecule doping/dedoping is the change color that can produce completely reversibility in the process of oxidation or reduction, such as polyaniline (PANI), polythiophene, polypyrrole etc., and organic conductive macromolecule exists good film-forming property, color tunable, low cost and other advantages, studies maximum PANI that still concentrate on.
At present, business-like electrochromic device all is " sandwich " type structure, as electrochromic, is about to the electrochromism thing and is clipped between two electrodes that include electrolyte, ion storage layer with coating or film mode.For change color is showed to external world, requiring wherein, at least one electrode is a transparency electrode.Commercially available transparency electrode has ITO/PET at present, soft not enough, thickness more greatly, the thinnest be 188 μ m, other possible electrode material has other defectives such as color or electrical conductivity are low such as conducting resinl, PEDOT/PSS, AZO electro-conductive glass, wire netting or lining etc. more.Therefore, providing a kind of can just become this technical field at the color-changing camouflage fabric of change between two kinds or the above camouflage pattern and preparation method thereof and be badly in need of the technical barrier that solves.
