Direct Femtosecond Laser Fabrication of Superhydrophobic Aluminum Alloy Surfaces with Anti-icing Properties

摘要: Ice formation is a serious issue in many fields, from energy to aerospace, compromising the devices’ efficiency and security. Superhydrophobicity has been demonstrated be correlated anti-icing properties of surfaces. However, fabricating surfaces with robust water repellence also at subzero temperature still great challenge. In this work, femtosecond laser (fs-laser) texturing exploited produce superhydrophobic on Al2024, an aluminum alloy interest cold environments, particular for aircraft production. Our textured substrates present self-cleaning repellency temperatures. Moreover, outstanding are achieved −20 °C, droplets bouncing off surface before freezing.
