Polymeric compositions useful in preventing the frost or ice deposition in the surface of wind turbine generator blades present in a cold climates or high altitude are provided. In addition to the anti-icing capacity, the polymeric composition prevents the deposition of dirt, i.e. it has self-cleaning properties.

Polymeric composition with anti-icing and self-cleaning properties

The invention provides a composite laminate comprising an outer, an intermediate and an inner section comprising, respectively, first layers of composite material and one or more functional layers having a printed circuit for absorbing the electromagnetic radiation incident on the composite laminate; second layers of composite material; a conducting layer contiguous to the intermediate section and third layers of composite material. The values of the resistivity of the functional layer and the thickness of the intermediate section are comprised in predefined ranges for the attenuation of the reflection of electromagnetic radiation of the composite laminate in the S or X bands up to a peak of &#x2212;20 dB. The invention also refers to manufacturing methods of the composite laminate () and to wind turbine blades including the composite laminate.
