ICE-ACCRETION AND SNOW-ACCRETION PREVENTIVE ANTENNA AND ELECTRIC WIRE, INSULATOR HAVING WATER-REPELLENT AND OIL-REPELLENT ANTI-FOULING SURFACES, AND THEIR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an antenna and electric wire which are extremely high in ice-accretion and snow-accretion preventing effect in a sever winter by realizing a surface which is not more than 2 mN/m in surface energy, thereby to prevent breakage of the antenna and disconnection of the electric wire caused by ice-accretion and snow-accretion. SOLUTION: The ice-accretion and snow-accretion preventive antenna and electric wire having the water-repellent and oil-repellent surfaces and their manufacturing method, characterized in that the surface of each base material is compositely worked to have large and small uneven portions and each surface is covered by a water-repellent and oil-repellent anti-fouling thin film. Preferably, the large uneven portion ranges from 500 to 10 microns in size and the small portion is less than 10 microns and 10 nm or above in size. COPYRIGHT: (C)2009,JPO&INPIT
