Description
Technical field:
The present invention relates to a kind of transparent conductive film, intelligent light modulation film and preparation method thereof, particularly a kind of transparent conductive film electrode for intelligent light modulation film and preparation method thereof, and relevant intelligent light modulation film and preparation method thereof.
Background technology:
Intelligent light modulation film is the photoelectric device that a kind of input by the signal of telecommunication changes its optical parametric such as light transmittance, mist degree.It is often used in the fields such as external wall, house property decoration, vehicle glass, automobile rearview mirror, projection curtain wall, office space, public entertainment facility.Smart window on the most typically application building of intelligent light modulation film, intelligent light modulation film by sticking, the mode such as clamping is combined with building glass, by to input electrical signal on intelligent light modulation film thus regulating from the incident light intensity of glass forms, and then reach energy-conservation purpose.
Usual intelligent dimming membrane module, is be made up of the light regulating course of two transparency conductive electrode material layers and middle clamping.The electrode material being widely used at present is tin indium oxide ITO electrode, and its basic structure is one layer of ITO conductive material of attachment in transparent substrates.But intelligent light modulation film is still difficult to commercially spread at present, reason is in that the core as intelligent light modulation film and transparent conductive electrode material there is also problems: one, the main component indium of ITO is scarce resource and expensive, the cost of raw material is higher, it is impossible to large-area applications is in construction material；Two, the processing of ITO conductive layer is realized by the method such as sputtering, evaporation mostly, not only energy consumption is high and also waste of raw materials seriously, cause that its technique manufacturing cost is very high；Three, ITO is a kind of oxide semiconductor material, and fragility is big, it is difficult to realize bending, the function such as folding, serious hinders its further application in smart window technology；Four, the reflectance of ITO is higher, and easily because illumination causes xanthochromia when preserving.
And emerging ITO substitution material Graphene is as a kind of Two-dimensional Carbon nano material, its thickness only has 0.34 nanometer, and it is almost fully transparent, only absorbs the light of 2.3%；Under room temperature, its electron mobility is more than 15000cm2/ Vs, and resistivity about 10-8Ω m, lower than copper or silver, it is the minimum material of current resistivity.Graphene transparency conductive electrode material has possessed the unrivaled advantage of ITO and performance, and carbon is extremely abundant in nature so that the cost of raw material of Graphene is also quite cheap.In theory, Graphene is to substitute ITO preferred plan.
But, transparent graphene conductive film is not but successfully applied in intelligent light modulation film field.One main cause is that current transparent graphene conductive film complicated process of preparation, lattice defect are many, and its higher surface resistance will produce serious pressure drop in larger-size intelligent light modulation film products application, cause the problems such as response time prolongation, cut-in voltage become greatly, variable color is uneven, energy consumption is higher.Thereby producing numerous composite conductive thin film to improve electric conductivity, mode the most frequently used at present is the composite construction adopting metal grill with Graphene.But it is applied on intelligent light modulation film and has serious drawback after metal mesh structure and Graphene compound, because metal mesh structure can be extra increase local height, being applied in increase light modulation film device breakdown probability on intelligent light modulation film causes the decline of product yield.Conventional screen mode of printing, inkjet printing mode standby metal grill, its grid height is commonly greater than 1 micron, require in more fine light modulation film structure at some, such as the thickness of whole light regulating course is less than 2 microns, so first, the metal grill of two electrodes is easy to contact with each other, and causes punch through.
For above-mentioned technical problem, it would be highly desirable to provide a kind of new composite conductive thin film, solve that conventional graphite alkene conductivity is low, the problem such as metal grill height causes in conventional composite thin film component failure.
