[0003] In Japan, the rapid aging of the population has led to a serious social problem with an increase in the elderly population. For denture users, including bedridden elderly who cannot brush their teeth, it is expected that the treatment to prevent contaminants from adhering to dentures will help to clean the oral cavity and maintain health. However, in the conventional method,
The water droplet contact angle was at most 100-115 °. At such a contact angle, water droplets and the surface are in contact with each other by about 30%, so that a pollutant adheres during a long-term use process, and there is a problem that initial performance is reduced. In addition, there are many processing steps, and a large amount of water and organic solvents are used.

[0009] By the surface modification of the substrate by the above treatment,
The effect that the water repellency is remarkably improved and the adhesion of pollutants is significantly suppressed is obtained. This phenomenon involves the physical treatment of artificially forming irregularities on the surface to increase the surface area and forming an air layer that is very difficult to wet, and the surface energy of the substrate surface by covering the surface with a material with low surface tension This is due to a synergistic effect with the chemical treatment of lowering the concentration, and it appears only when these two treatments are combined. The unevenness due to the physical processing is desirably 50 nm or more. Because 50n
If it is less than m, water droplets enter into the unevenness and a sufficient air layer cannot be secured, so that water repellency is not improved. Further, the unevenness is desirably less than 500 nm. This is because when the thickness is 500 nm or more, the contaminants are more likely to adhere irregularly. The reason that the treated substrate exhibits high antifouling substance adhesion is, as described above, due to the combination of the physical treatment and the chemical treatment,
It is presumed that the chemical effect is exhibited by the synergistic effect of the chemical effect of the fluorocarbon chain or long-chain alkyl chain immobilized on the treated surface and the physical effect of the unevenness present on the treated surface. By the pollutant substance adhesion suppressing treatment of the present invention, adhesion of the pollutant substance to the base material can be suppressed, and deterioration of the base material, discoloration, deterioration of the initial performance, and the like in the use process can be reliably prevented.
