摘要
Conventional chemisorption films use only a chemical bond between an adsorbent and a flat base material surface and thus have a problem that the contact angle of water droplets is about 120 degrees at the highest and, thus, water repellent, oil repellent and anti-fouling properties and water take-off properties are unsatisfactory for spontaneous removal of water droplets and dirt as in a lotus leaf. This invention provides an icing and snow accretion preventive insulator, electric wire and antenna. They are manufacture by a method characterized by comprising at least the step of forming a fine particle fusion film on the surface of a base material, the step of coating a fine particle liquid, prepared by dispersing fine particles in a solvent which does not dissolve the film, and drying the coating, the step of firing, the step of removing, by washing, fine particles not fused to the film, and the step of forming a water repellent, oil repellent and anti-fouling film. Alternatively, they may be manufactured by a method characterized by comprising at least the step of coating a fine particle liquid, prepared by dispersing fine particles in a solvent, onto the surface of a base material and drying the coating, the step of firing, the step of removing, by washing, fine particles not fused to the film, and the step of forming a water repellent, oil repellent and anti-fouling film.
