Definitions
- the present invention relates to a composite material in which a surface containing a photocatalytic substance is formed on a surface of a member such as a substrate, a lens, a glass plate, a mirror, or the like to make the surface of the member hydrophilic or stain-resistant. Is improved. Background art
- the T I_ ⁇ 2 film 4 is provided between the S I_ ⁇ 2 film 6 and the substrate 2, the photocatalytic decomposition action of T i O 2 film 4, the dirt adhered to the surface of S i O 2 film 6 decomposition and, by keeping the surface of the S I_ ⁇ 2 film 6 clean, so as to maintain the hydrophilicity.
- Figure 3 is changed in the conventional structure, S i 0 2 film b 'nm, T I_rei_2 film thickness of 4' 5 0, 1 0 0, a 1 5 0, 2 0 0 nm in Figure 2
- Fig. 4 is a graph showing the spectral reflectance characteristics in the visible region (380 to 780 nm) when subjected to light.
- FIGS. 3 and 4 are graph showing the spectral transmittance characteristics of a similar sample. As shown in FIGS. 3 and 4, when the thickness of the Ti ⁇ 2 film 4 is 50 nm, relatively flat reflectance and transmittance characteristics are obtained. At 00, 150, and 200 nm, large amplitudes occur in the reflectivity according to the change in wavelength.
- Table 1 shows samples of the conventional structure shown in Fig. 2 in which the thickness of the Ti ⁇ 2 film 4 is 50, 100, and 150 nm, respectively, as in Figs. 3 and 4. The graph shows the initial contact angle and the contact angle after 4 hours of irradiation with black light (intensity l mW / C m 2 ) when oil was applied to the surface of each member.
- the thickness of the photocatalytic reactant film 4 was set to 1 in order to obtain a photocatalytic decomposition action for maintaining hydrophilicity. More than 0 nm was required. And power, and, as shown in FIG. 3, T I_ ⁇ thickness of 2 film 4 1 0 0, 1 5 0, the 2 0 0 nm, coloring effect on the member surface for a large amplitude occurs in the spectral characteristics Will occur. This is because optical interference in a visible light region to the T i O 2 film 4 by the thickness of the T I_ ⁇ 2 film 4 is formed thick occurs. If the amplitude of the spectral characteristic is large, the original color tone of the member surface is damaged. In addition, a large amount of photocatalytic substance material was required for the provision of a thick film.
- the present invention has been made in view of the above points, and it is possible to obtain sufficient antifouling property or hydrophilicity even if the photocatalytic substance film is formed thinner than before, and
- An object of the present invention is to provide a composite material capable of suppressing the interference of light in a material film and reducing the amount of photocatalytic material used.
- the present invention comprises a base material, a transparent metal thin film provided on the surface of the base material, and a hydrophilic functional layer containing a photocatalytic substance provided on the surface of the transparent metal thin film. According to experiments performed by the inventors, it has been found that providing a transparent metal thin film improves photocatalytic properties. As a result, the hydrophilic functional layer containing the photocatalytic substance can be formed thinner than before. Also, since water-proof or hydrophilic properties can be obtained, the amount of the photocatalytic substance used can be reduced.
- the hydrophilic functional layer containing the photocatalytic substance thinly, light interference in the hydrophilic functional layer containing the photocatalytic substance can be reduced, and the original color tone of the base material can be maintained. it can.

- the first and second transparent electrode films 54, 56 force S from being corroded by the solvent of the liquid-phase electrochromic layer 52, the first and second transparent electrode films 54, 5
- An electrode protection layer made of SiO 2 or the like having optical transparency may be provided between the liquid crystal electrode port chromic layer 52 and the liquid phase electrode port chromic layer 52.
- the composite material according to the present invention can be used as an anti-fog mirror for an automobile outer mirror by applying to a mirror, and can also be used as a colored anti-fog mirror whose reflective surface is colored. It can also be used as an electrochromic anti-glare anti-fog mirror. Also, it is configured as a light-transmitting colored anti-fog substrate without a reflective film, and is used as a lens or window, or as a chromic anti-fog member for a light-transmitting liquid-phase electoric port and used as a light control window, etc. You can also.
