Superhydrophobic Epoxy/Fluorosilicone/PTFE Coatings Prepared by One-Step Spraying for Enhanced Anti-Icing Performance

The icing of glass insulators is likely to cause faults such as insulator flashover, which poses a serious threat the power system. Traditional deicing techniques have disadvantage being costly and inefficient. Herein, polytetrafluoroethylenes (PTFEs) nanoparticles epoxy fluorosilicone resins binders were blended construct an anti-icing coating. superhydrophobic (SHP) epoxy/fluorosilicone/PTFE coatings for successfully prepared on slides through one-step spraying. effect PTFE mass fraction microstructure, wettability properties was investigated. results showed that with different fractions had microstructures. When 47.2%, SHP coating exhibited uniform rough structure apparent contact angle high 164.7° sliding low 3.2°. Moreover, water droplets can bounce back five times time only 9.5 ms rebound height 4.58 mm. In low-temperature environment (−10 °C), displayed good anti-frosting, icephobic properties. delayed frosting (1499 s) freezing (1295.3 three longer than those glass, respectively. presented ice-adhesion strength (39.8 kPa) six lower glass. demonstrated potential applications insulators.
