Abstract
The invention provides a wind turbine component having an exposed surface made of a hydrophobic material and having a surface texture providing a Water Contact Angle (CA) of at least 150. Due to the combination between a CA over 150 and the hydrophobic material, the component becomes less vulnerable to ice formation etc. The invention further provides a method of preventing ice formation, a method of reducing noise and a blade for reducing noise from a wind turbine.

A wind turbine component having an exposed surface made of a hydrophobic material and having a surface texture providing a Water Contact Angle (CA) of at least 150.
A method of providing anti-icing properties on an exposed surface of a wind turbine component, the method comprising applying a layer of a hydrophobic paint to the exposed surface and arranging granular particles in the paint such that the particles project from the layer of paint.
A blade for reducing noise in operation of a wind turbine, the blade having an exposed surface made of a hydrophobic material and having a surface texture providing a Water Contact Angle (CA) of at least 150.
A method of reducing noise in a wind turbine, the method comprising applying a layer of a hydrophobic paint to the exposed surface, and arranging granular particles in the paint such that the particles project from the layer of paint.
