Ultra short laser pulse generation of anti-ice surfaces
conference paper
Wetting properties of many materials can be changed by accurate laser micromachining with ultra short laser pulses (USLP). USLP machining provides a method for creating a surface topography with the specific micro and sub-micrometer scale features which are required for creating water-repellent surfaces. These structures with a high water contact angle and low contact angle hysteresis remain dry, and can be used as anti-ice coatings because of its reduced ice-adhesion strength and easy water roll off. This paper investigates the potential anti-ice properties of laser machined designed patterns with changing geometries, in combination with a CVD deposited hydrophobic coating. The result of a highly adjustable surface topography and a reduced surface energy yields extraordinary water repellent properties.
