Superomniphobic Surfaces for Military Applications: Nano- and Micro-Fabrication Methods. Chapter 2: Investigation of Wear for Superhydrophobic Surfaces and Development of New Coatings

Abstract

The results of wearing superhydrophobic surfaces and its effect on roughness parameters, surface properties and wetting behaviour are described in this report. An abrasive wear device has been set up to allow consistency, reproducibility and precise control over the amount of wear desired. Based on the results obtained, relationships in the trends observed with the different roughness parameters and wetting behaviour have been established. In some cases the relationships are strong while in other cases, the relationships are weak and unable to capture the different transitions in wetting. It has also been determined that different roughness scales present on a surface wear differently and require separate attention. This knowledge is partly applied in the development of a versatile superhydrophobic coating that can be used on smooth and rough materials ranging from glass and aluminum, to polyester/nylon, cardboard and wood.
