For insulator in transmission line project of low temperature anti icing requirements on glass substrates by low temperature super hydrophobic PTFE films by reactive magnetron sputtering, to study the effects of sputtering parameters on the properties of the superhydrophobic films, and explores the superhydrophobic properties of thin films at low temperature. The wettability, surface morphology, film thickness and roughness of the film surface were characterized by water contact angle measuring instrument, scanning electron microscope and surface profiler respectively. The results show that the PTFE films prepared by magnetron sputtering have excellent hydrophobic properties, and the maximum static water contact angle of the films is up to 170 degrees + 3 degrees, and the superhydrophobic properties can be maintained at low temperature.[url=http://customvacuumfurnace.com/furnace-manufacturers/Good-Service-Designed-Hydrogen-Sintering-Furnace-Vacuum.html]Good Service Designed Hydrogen Sintering Furnace Vacuum[/url] The surface of superhydrophobic film refers to the material's static contact angle (i.e., water contact angle) greater than 150 degrees and the rolling angle is less than 10 degrees. Because the water droplets are difficult to
