In the process of implementing the application, the applicant finds that the pure ITO film of the existing electromagnetic shielding and electromagnetic stealth film layer is difficult to plate a low-resistance (surface resistance is less than 5 Ω/□) conductive film due to high resistivity, the lower the surface resistance is, the larger the corresponding film layer thickness is, and the problem of large stress exists in an excessively thick film layer. The gold film has obvious attenuation on the visible light transmittance, and the transmittance is lower under the condition of the same surface resistance. Both the pure ITO film and the gold film do not achieve ideal i properties of low resistance and high transmittance. The existing silver-based film is mainly used for a Low-E film of building glass, the film system is complex in structure, the stacking can be realized only by coating films of dozens of coating chambers on a large-scale production line, the required products can be finally realized only by independently and accurately controlling the material and the coating thickness of each coating chamber (the thickness requirements of all layers are different), and meanwhile, because the surface of the traditional silver-based film is sealed without an organic coating, the silver film is extremely easy to oxidize and cannot be used as a bare film, the film can be used only by adopting a hollow glass structure or a laminated glass structure.

Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
As used herein, "first," "second," and the like, are not specifically intended to be construed in an orderly or sequential sense, nor are they intended to be limiting, but merely to distinguish between elements or operations that are described in the same technical language.
Please refer to fig. 1 and fig. 2, which are two schematic diagrams of the silver-based electromagnetic shielding and electromagnetic stealth film system structure according to an embodiment of the present application. As shown, the silver-based electromagnetic shielding and electromagnetic stealth film system structure 1 includes a base 2 and at least one functional unit 3. At least one functional unit 3 is stacked on the base body 2. In this embodiment, the number of the functional units 3 is three, the three functional units 3 are sequentially stacked on the inorganic glass, and the thicknesses and materials of the film layers of the three functional units 3 are completely the same, so that the three functional units can realize good process control in the single-chamber coating kettle. In one embodiment, as shown in fig. 1, an inorganic glass is used for the base body 2, and three functional units 3 are sequentially stacked and disposed on the inorganic glass. In another embodiment, as shown in fig. 2, the organic glass 21 and the base coat 22 are used as the substrate 2, the base coat 22 is disposed on the organic glass 21, and the three functional units 3 are sequentially stacked on the base coat 22, but not limited thereto.
Referring back to fig. 1 and 2, each of the functional units 3 includes a first dielectric layer 31, a silver film 32, a metal protecting layer 33, and a second dielectric layer 34. The silver film 32 is disposed on the first dielectric layer 31, the metal passivation layer 33 is disposed on the silver film 32, and the second dielectric layer 34 is disposed on the metal passivation layer 33. The first dielectric layer 31, the silver film 32, the metal protection layer 33 and the second dielectric layer 34 can realize the film coating of the functional unit 3 by adopting 3 targets in one film coating chamber, so that the complete film coating is realized in a single-cavity film coating kettle, the traditional silver-based film system is greatly simplified, and the production and quality control are more favorably realized.
In the present embodiment, the material of the first dielectric layer 31 and the second dielectric layer 34 includes one or more of zinc oxide, tin oxide, zinc tin oxide (doped), zinc aluminum oxide (aluminum doped), titanium oxide, indium tin oxide (doped), and indium zinc oxide (doped). The thickness of the first dielectric layer 31 and the second dielectric layer 34 is 30-50nm, preferably 40nm, but not limited thereto. The thickness of the silver film 32 is 7 to 15nm, preferably 10nm, but not limited thereto. The metal protective layer 33 is a metal titanium film or a nickel-chromium alloy film (nickel: chromium ═ 4:1), preferably a metal titanium film, and the thickness of the metal protective layer 33 is 1 to 5nm, preferably 1 nm.
Please refer to fig. 3, which is a schematic diagram illustrating a functional unit in a film plating state according to an embodiment of the present application; as shown in the figure, when the functional unit 3 is used for coating in the coating chamber S, 3 targets are selected and placed in the movable tray S1, wherein the first target S01 corresponds to the first medium layer 31 and the second medium layer 34, the second target S02 corresponds to the silver film 32, and the third target S03 corresponds to the metal protection layer 33, the first target S01 is firstly opened and the second and third targets are closed, after the first medium layer 31 is coated, the second target S02 is opened and the first and third targets are closed, after the silver film 32 is coated, the third target S03 is opened and the first and second targets are closed, and after the metal protection layer 33 is coated, the first target S01 is finally opened and the second and third targets are closed, and the second medium layer 34 is coated.
As described above, when each layer of film is coated, the reciprocating coating is realized by reciprocating the movable tray S1, the speed and time of the reciprocating movement depend on the thickness requirement of each film structure, and the linear stacked coating can be performed by setting the reciprocating program of the silver-based functional unit by the program. In addition, the structure of the functional unit 3 of the present embodiment can achieve a high light transmission effect by repeated stacking according to the antireflection structure of the film member, while achieving a requirement for low resistance due to the excellent conductivity of the silver layer. When a single functional unit 3 is plated on the substrate 2, the surface resistance can reach 5-10 omega/□, the visible light transmittance is greater than 80%, and the performance of the functional unit is basically close to that of the existing ITO film, but the performance cannot meet the requirements of low resistance and high transmittance. In order to reduce the sheet resistance of the film layer without affecting the visible light transmittance, a plurality of functional units may be stacked on each other.
Under the condition that the thickness of each layer of the functional unit 3 is kept unchanged, when repeated stacking coating is carried out, when two functional units are stacked, the visible light transmittance can be kept above 80%, and meanwhile, the surface resistance can be reduced to 2-4 omega/□; when three functional units 3 are stacked, the visible light transmittance can be kept above 80%, and the surface resistance can be reduced to 1-2 omega/□; when four functional units 3 are stacked, the surface resistance can be reduced to 1 Ω/□ or less, but the visible light transmittance is reduced to 75%.
It should be noted that, as the functional units are further stacked in more than four layers, the surface resistance can be further reduced, but the reduction range of the surface resistance is reduced, the visible light transmittance is further attenuated, and the more the number of stacked layers, the greater the visible light transmittance is, so that the electromagnetic shielding and electromagnetic stealth films of the 3 functional units 3 are stacked, the surface resistance and the visible light transmittance can achieve the comprehensive optimal effect, meanwhile, the 3 functional units 3 of the embodiment are thinner, the total thickness of the functional units is not more than 300nm, and the total thickness of the conventional ITO electromagnetic shielding and electromagnetic stealth films exceeds 600 nm. The thinner film layer can reduce the internal stress of the film layer, the low internal stress corresponds to stronger aging performance, and the electromagnetic shielding and electromagnetic stealth film product of the embodiment has better aging performance.
For the traditional silver-based film system, the traditional silver-based film system is not provided with an organic coating protective film, if the silver-based film is exposed to the atmospheric environment, the silver-based film can be corroded and oxidized by oxygen and water vapor in the air in a short time, and the traditional silver-based Low-E film can only be used through a hollow structure and a gluing structure of glass. This embodiment sets up one deck organic coating protection film 4 on outermost functional unit 3, and organic coating protection film 4 possesses waterproof, grease proofing, the function of resistant fish tail, can be fine with silver-based rete seal protection to can realize monolithic glass and use, save a large amount of material cost and processing cost, can lighten glass's weight by half simultaneously, this characteristic is favorable to the application in aerospace field more.
Specifically, the organic coating protection film 4 is made of polyurethane, organic silicon or acrylic acid organic coating, the main component of the organic coating protection film is polyurethane, a polyurethane organic coating with the thickness of about 20-100 μm is manufactured on the outermost functional unit 3 by adopting a wet curtain coating process, the polyurethane coating can form a film structure with stable structure and firm film adhesion with a zinc oxide film, can form strong protection on the internal functional film, and can completely block the oxidation corrosion effect of external oxygen and water vapor on the functional film.
To sum up, the application provides a silver-based electromagnetic shielding and electromagnetic stealth membrane system structure, and it can realize the coating film and pile up in single chamber coating film cauldron, so conveniently realize production and quality control. Meanwhile, after the functional units are stacked for three times, the surface resistance is about 1-2 omega/□, the visible light transmittance is not lower than 80%, and the uniform requirements of low resistance and high light transmittance are met.
