Features of Using Nanostructured Plastic Polymer Coatings for Protection against Icing of Industrial Structures

The results of studies of superhydrophobic surfaces under conditions of icing on a climatic aerodynamic stand are summarized. The prospects and limitations of using plastic polymer coatings for anti-icing systems of wind turbine blades are shown. The effect of destruction by ice of superhydrophobic surfaces with coatings with nanograss and nanooutgrowths in an aerodynamic flow has been investigated. The resistance to destruction by icing has been established only for linear microstructures imitating depressions on the nanostructure in the form of lotus leaves. A simple mathematical model has been adapted to illustrate the effectiveness of various nanostructured formations on a solid surface in dependence on the blowing speed and wetting angle. The results obtained are of interest for development of anti-icing systems for structures with plastic coatings (wind turbine blades, protective plastic elements of bridges, oil platforms, etc.).
