There are many different strategies for maintaining ice-free surfaces, ranging from chemical modification at a molecular level to targeted structuring of the surface and classic electrothermal heating systems. Transferring these approaches to optically high-quality and transparent safety windows represents an additional challenge. This is to be achieved by using nanoscale materials that pose particular challenges in terms of processing. Transparent coatings are currently being developed for ice protection systems for helicopter windows (HEATS - heatable, anti-ice-functionalised and transparent composite safety windows, funded by the BMWK in the LuFo VI-1 programme; FKZ: 20Q1960B). The multi-layer structure is to contain functions for ...
