Abstract

PROBLEM TO BE SOLVED: To provide a guard fence hard to be fouled by forming a surface layer having structure microscopically dispersed both of a part showing a hydrophilic property where photocatalytic oxide particulates are exposed to make contact with outside air and a part showing water repellency where water repellent fluorine contained resin is exposed to make contact with the outside air on a surface of a base material. SOLUTION: A surface layer having structure microscopically dispersed both of a part showing a hydrophilic property and a part showing water repellency due to water repellent fluorine contained resin is formed on the surface of a base material. Consequently, hydrophilic attachments are made not to become attached to the part showing water repellency, and hydrophobic attachments are made not to become attached to the part showing the hydrophilic property. Additionally, photocatalytic oxide particulates are made to exist on the part showing the hydrophilic property and the hydrophilic property of the part showing the hydrophilic property is maintained in accordance with light excitation. Consequently, neither a hydrophilic attaching matter nor a hydrophobic attaching matter is fastened on a surface of a member, and it is possible to maintain the surface in a clean state.

And a surface layer having a structure in which both of the water-repellent portions exposed so as to be in contact with the surface are microscopically dispersed on the surface is formed. In such a structure, since the hydrophilic surface and the water-repellent surface are adjacent to each other, the hydrophilic adherent that easily adapts to the hydrophilic surface does not adapt to the adjacent water-repellent portion. Conversely, hydrophobic deposits that are easily adapted to the water-repellent surface do not adapt to adjacent hydrophilic portions. Therefore, neither the hydrophilic deposit nor the hydrophobic deposit is fixed to the member surface, and the surface is maintained in a clean state. Furthermore, the presence of the photocatalyst causes the photocatalytic oxide particles to be exposed so as to be in contact with the outside air in response to the photoexcitation of the photocatalyst, so that the hydrophilic portion is permanently maintained. The structure in which both the water-repellent and water-repellent portions are microscopically dispersed on the surface is maintained.

Then, cloudiness due to irregular reflection of light can be prevented, and the surface layer becomes substantially transparent. Further, it is more preferable that the thickness of the surface layer be 0.2 μm or less. Then, it is possible to prevent the surface layer from being colored by light interference. Also, the thinner the surface layer, the better its transparency. Further, when the film thickness is reduced, the wear resistance of the surface layer is improved.

Whether or not it has the structure described above can be confirmed by the following method. One such method is performed as follows. That is, first, a solution containing a metal having a large atomic number such as Ag, Pt, or Pd such as silver nitrate, silver lactate, chloroplatinic acid, or palladium chloride is applied to the substrate surface, and the substrate surface is irradiated with excitation light of a photocatalyst. Ag, P
A metal having a large atomic number, such as t or Pd, is deposited on the substrate surface. Since the deposition reaction of the metal is based on the reduction action of the metal by the photocatalyst, at this time, the metal adheres to the hydrophilic portion exposed by the photocatalytic oxide particles in contact with the outside air, but the water-repellent fluororesin Is hardly adhered to a portion exhibiting water repellency exposed so as to be in contact with the outside air.
Next, by observing the reflected electron image of the scanning electron microscope, if the density (contrast) is dispersed, the photocatalytic oxide particles are exposed so as to be in contact with the outside air and exhibit a hydrophilic property. It is concluded that both the water-repellent portions exposed so that the fluororesin comes into contact with the outside air have a structure microscopically dispersed on the surface. As another observation method, elemental analysis of the surface may be performed using an energy dispersive X-ray analyzer (EDX) or an electron probe microanalyzer (EPMA) instead of observing the density using a backscattered electron image. . As another observation method, if the metal is colored such as silver, the color may be observed by an optical microscope instead of observing the density by a reflected electron image.

It can be fixed by a method such as a combination of pressure treatment and the above heat treatment, or fixing by impact pressure. Further, before fixing by the above method, the surface of the substrate may be blasted or the like to provide irregularities. Then, the adhesion between the substrate and the surface layer can be improved.
