Embodiment approach 1

[0062] Fig. 1 is a cross-sectional view of Embodiment 1 of the anti-fog material of the present invention. On the surface of a light-transmitting plate material 22 such as resin or glass, films such as Cr and Rh are formed by vacuum coating or sputtering. 24. On the surface of the transparent metal film 24, a hydrophilic functional layer 26 containing a photocatalytic substance is provided. The hydrophilic functional layer 26 that contains photocatalytic substance is from the side of transparent metal film 24, will contain TiO 2 Photocatalytic layer 28 of photocatalytic substances such as SiO 2 The hydrophilic layer 30 of a hydrophilic material such as a vacuum coating method or a method such as sputtering is laminated to form a film. In the present embodiment, in order to increase hydrophilicity, it is preferable to form a porous state on the surface of the hydrophilic layer 30 containing a hydrophilic substance.

[0063] Prepare the transparent metal thin film 24 in the st...

Embodiment approach 2

[0082] 10 is a cross-sectional view showing Embodiment 2 of the composite material of the present invention. On the surface of the light-transmitting plate material 22, transparent metal films 24 such as Cr and Rh are used to form a film by vacuum coating, and then the transparent metal film 24 is formed into a film. Surface, adopt vacuum coating method or sputtering method to form TiO 2 etc. The film 32 of the hydrophilic layer of the photocatalytic substance.

[0083] Because TiO 2 The photocatalytic substance such as is excited by light and produces hydrophilicity, in embodiment 2, because the hydrophilic layer 32 of photocatalytic substance is made of having TiO 2 Such a hydrophilic photocatalytic substance is formed, the surface of the material is hydrophilized, and the hydrophilicity can be maintained by photocatalytic decomposition. Furthermore, in the present embodiment, in order to increase hydrophilicity, it is preferable that the surface of the photocatalytic subs...

Embodiment approach 3

[0085] Fig. 11 is a cross-sectional view showing Embodiment 3 of the composite material of the present invention. On the surface of the light-transmitting plate material 22, transparent metal films 24 such as Cr and Rh are used to form a film, and then on the surface of the transparent metal film 24, vacuum coating is used. method to form TiO-containing 2 and other photocatalytic substances and SiO 2 A hydrophilic substance mixed layer 34 such as a photocatalytic substance and the like is formed into a film, and it is preferable to form a porous state on the surface of the mixed layer 34 containing a photocatalytic substance and a hydrophilic substance.

[0086] In the structure shown in FIG. 11, since the mixed layer 34 containing the photocatalytic substance and the hydrophilic substance is formed, the surface of the material is hydrophilized, and the hydrophilicity can be maintained by photocatalytic decomposition.

[0087] In addition, on the back of the light-transmittin...

Abstract

On the surface of a light-transmitting plate material 22, a transparent metal thin film 24 is provided, and further, on the surface of the transparent metal thin film 24, a hydrophilic functional layer 26 containing a photocatalytic substance is provided. The hydrophilic functional layer 26 comprises a laminate of, from the side of the transparent metal thin film 24, a photocatalytic layer 28 containing a photocatalytic substance and a hydrophilic layer 30 containing a hydrophilic substance.

Description

technical field [0001] The present invention relates to a composite material, which forms a film layer containing a photocatalytic substance on the surface of a substrate or a lens, a glass plate, a mirror, etc., so that the surface of the material has hydrophilicity or antifouling property, especially relates to a hydrophilic Composite materials with high durability or antifouling properties. Background technique [0002] The technique of keeping the surface of a material clean due to the formation of a layer of photocatalytic substances on the surface of the material is known. That is, by the photocatalytic action of the photocatalyst substance layer on the surface of the material, the dirt attached to the surface of the material is decomposed, and the dirt is easily removed by washing with water or the like. [0003] As a composite material using material surface purification technology in the above-mentioned photocatalytic substance layer, the applicant has proposed the...
