Large-area fabrication of a hierarchical coating via a roller painting process toward an efficient, durable and scalable anti-icing surface
PROGRESS IN ORGANIC COATINGS(2024)
摘要
A hierarchical coating was fabricated via a roller painting method with a layer of fluorine -modified boron nitride (fBN) nanoparticles buried in a porous network of Al2O3 microparticles bridged by a fluorocarbon (FC) resin. The sticky FC resin made the fBN nanoparticles firmly locked in the cavities and this enhanced structural stability of the Al2O3-based porous network. This enabled the formation of a superhydrophobic coating with excellent resistance to environmental erosion and high thermal conductivity. The de-icing temperature of this coating was lowered by 22.2 C-degrees in comparison with a conventional superhydrophobic coating. A case study showed a potential of applying this coating onto large -sized uneven surface like turbine blades.
