Investigation of the Mechanical and Chemical Stability of Superhydrophobic Coatings Based on Reactive Copolymers of Glycidyl Methacrylate and Fluoroalkyl Methacrylates

Abstract

This work is devoted to studying the stability of polymer coatings formed from reactive copolymers of glycidyl methacrylate and fluoroalkyl methacrylates and applied onto textured aluminum and cotton textile surfaces. The stability is determined with respect to the action of aggressive media and mechanical stress. The resulting coatings provide the achievement of long-term stable heterogeneous wetting with initial contact angles as large as 170°, thus preventing the penetration of corrosive agents into the hierarchical structure. The study has shown the influence of the composition of the reactive copolymers containing 3–7 fluorine atoms in a monomer unit on the stability of the polymer coatings with respect to the prolonged exposure to media with different acidities, as well as to cavitation, and abrasive wear.
