Anti-icing: Surfaces, technical approaches and status
Abstract
Ice accretion on surfaces and its prevention have been investigated for a long time by work groups all over the world with a limited success to date. A more realistic current goal is the production of durable, industrially-viable coatings which function by reducing ice adhesion forces rather than by completely preventing the formation of ice. Besides carrying out research on these (passive acting) coatings, specialists at the Fraunhofer Institute for Manufacturing Technology and Applied Materials Research (IFAM) are developing new nano-structured surfaces with outstanding anti-ice effect. Another approach is the development of temporary active anti-ice coatings and the biomimetic coating concept which uses a biological model for technical coatings. The research on the development of anti-ice coating concepts is carried out by the Paint Technology department of the Fraunhofer IFAM. This paper summarises the work including reliable test methods (ice chamber tests, adhesion tests and investigations under real icing conditions) and has been completed with the latest results. The following approaches are described: new techniques for nano-structuring of surfaces and its anti-ice effect; biomimetic anti-ice coatings with the inclusion of anti-freeze proteins; temporary anti-ice Coatings and their area of application; hydrophobic coatings.
