Ice and snow accretion-preventive antenna, electric wire, and insulator having water-repellent, oil-repellent, and antifouling surface and method for manufacturing the same

摘要

A representative embodiment prevents breakage of antennas and accidents due to breakage of electric wires caused by ice and snow accretion by realizing a surface with a surface energy of 2 mN/m or less and providing an antenna and electric wire having an extremely great effect of preventing ice and snow accretion at midwinter.;Another representative embodiment provides an ice and snow accretion-preventive antenna and electric wire wherein a surface thereof is compositely fabricated to have large roughness and small roughness, and the surface of each of the roughness is coated with a water-repellent, oil-repellent, and antifouling thin film.
