Description

The high demand for prevention of ice formation and de-icing in a broad range of applications including transport, robotics, photovoltaics, and telecommunications requires new sustainable, cost-efficient, and effective solutions. Whilst active de-icing is key in various industry sectors, the development of de-icing method faces compatibility challenges with existing devices and real-world conditions. The recent employment of acoustic waves (AWs), in particular surface acoustic waves (SAW) for de-icing or anti-icing has proven to be a very promising approach and may open the path for a powerful alternative to the conventional solutions, especially for transparent materials or such with low heat conductivity. Our research addresses the de-icing of several mm thick ice layers on substrates with several centimeter side length using nanoscale activation through surface acoustic waves (SAWs). By combining SAW technology with passive hydrophobic coatings, we enhance the overall performance and sustainability of the approach. Additionally, the use of superstrates enables efficient deicing across diverse surfaces such as transparent substrates and aluminum. This integrated strategy offers a scalable solution for real-world applications.
