Embodiment

[0121] Hereinafter, although an Example demonstrates this invention, this invention is not limited to this.

[0122] Method for measuring and evaluating physical properties of laminates comprising organic-inorganic hybrid films

[0123] (i) Visible light transmittance

[0124] The visible light transmittance was measured using a Shimadzu Corporation spectrophotometer "SolidSpec-3700" (trade name) in accordance with the visible light transmittance test in 6.4 of JIS A5759:2008.

[0125] (ii) UV transmittance 1 (UV transmittance at a wavelength of 380nm)

[0126] According to the ultraviolet transmittance test of 6.4 of JIS A5759:2008, the transmittance at a wavelength of 380 nm is read from the transmittance spectrum measured using a spectrophotometer "SolidSpec-3700" (trade name) of Shimadzu Corporation, and the value is As UV transmittance 1.

[0127] (iii) Water contact angle

[0128] For the organic-inorganic hybrid film surface of the laminate, use the automatic contac...

example 1

[0141] (1) Use APP company's atmospheric pressure plasma treatment device "MyPL Auto200" (trade name), will contain 0.5 volume % of oxygen (O 2 ) of argon (use argon at a volume flow rate of 6 liters / minute, use oxygen (O 2 )) As the discharge gas, under the conditions of input power 180W, scanning times of 0.5 reciprocating, scanning speed of 20mm / sec, and distance between the electrode and the surface to be treated of 2mm, the above (C-1) was subjected to surface treatment.

[0142] (2) Next, using the diode sputtering device of VIC International Corporation, using the above-mentioned (A-1) and the above-mentioned (B-1) as targets, at a film formation pressure of 1Pa, the introduction gas is argon gas of 100% by volume (Table marked as "Ar" in ), the volume flow rate of the introduced gas is 10sccm, the distance between the above (C-1) and the target is 5cm, the input power (frequency 13.56MHz) is 540W on the above (A-1) side, and the above Sputtering film formation was sim...

example 2～7

[0146] Except for changing the input power at the time of film formation as shown in Table 1, in the same manner as in Example 1, the production and physical properties of a laminate including an organic-inorganic hybrid film were measured and evaluated. The results are shown in Table 1.

[0147] [Table 1]

[0148] Table 1

[0149]

[0150]

[0151] From these results, it was confirmed that the organic-inorganic hybrid film of the present invention having a low ultraviolet transmittance and a high visible light transmittance was obtained. In addition, the organic-inorganic hybrid membrane of the present invention has a hydrophobic function.

[0152] In addition, in the above-mentioned examples, a laminated body including the organic-inorganic hybrid film of the present invention was obtained using a glass plate as a base material. However, the organic-inorganic hybrid film of the present invention has low ultraviolet transmittance, high visible light transmittance, an...

Abstract

In one aspect, the present invention is an organic-inorganic hybrid membrane of a cerium oxide and an organic fluorine compound, the organic-inorganic hybrid membrane satisfying the following (a), (b), and (c): (a) the visible-light transmittance is 70% or higher; (b) the UV transmittance at a wavelength of 380 nm is 60% or lower; and (c) the water contact angle of the surface of the organic-inorganic hybrid membrane is 80 degrees or higher. In another aspect, the present invention is an organic-inorganic hybrid membrane of a cerium oxide and an organic fluorine compound, the organic-inorganichybrid membrane satisfying the following (a), (b), and (c'): (a) the visible-light transmittance is 70% or higher; (b) the UV transmittance at a wavelength of 380 nm is 60% or lower; and (c') the water contact angle of the surface of the organic-inorganic hybrid membrane is 90 degrees or higher. The organic fluorine compound may include a fluorine-based resin. Also disclosed are a laminate and anarticle that include the organic-inorganic hybrid membrane.

Description

technical field [0001] The invention relates to an organic-inorganic hybrid film. More specifically, the present invention relates to an organic-inorganic hybrid film having a low transmittance of ultraviolet light and a high transmittance of visible light. Background technique [0002] In the past, due to the need to meet the characteristics of good chemical stability, transparency, rigidity, scratch resistance and weather resistance, it has been widely used in automobile windows and windshields, doors and windows of buildings, protective plates of image display devices and display Products using inorganic glass as a base material are used for panels and the like. On the other hand, inorganic glass has the disadvantages of poor impact resistance and brittleness. Therefore, conventionally, a resin film is pasted on the inorganic glass in order to protect the inorganic glass from impact and to prevent scattering when the inorganic glass is broken. [0003] When pasting a r...
