摘要：
Aircraft propellers may encounter various harsh environments due to regional differences and weather changes during their service. Therefore， ideal rubber composites for aircraft propellers must have excellent superhydrophobic properties，delayed icing performance and environmental durability. In this paper，the silicone rubber superhydrophobic surface was prepared via the template method and high temperature treatment. The effects of low-temperature freezing， high-temperature heating and UV irradiation on the hydrophobic properties of superhydrophobic silicone rubber were investigated. In addition， the self-assembled delayed icing device was implemented to reveal the delayed freezing behavior of the superhydrophobic silicone rubber under the influence of moisture in the air. Scanning electron microscopy（SEM）and energy dispersive spectrometer（EDS）were employed to elucidate changes in superhydrophobic properties and delayed freezing mechanisms. The results show that the as-prepared superhydrophobic silicone rubber has demonstrated remarkable environmental durability and delayed freezing performance. It has important practical application value in superhydrophobic electric heating anti-icing of aircraft propeller. © 2023 Nanjing University of Aeronautics an Astronautics. All rights reserved.
