用于改善飞机螺旋桨防结冰性能的硅橡胶超疏水表面耐久性和延迟结冰性能研究
Durability and Delayed Icing Performance of Silicone Rubber Superhydrophobic Surface Used to Improve Aircraft Propeller Anti-icing Performance
摘要
Abstract
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.关键词
