Abstract

A superhydrophobic (SH) surface has many characteristics - of which are its self-cleaning and anti-corrosion functionalities - that are desirable across various industries. A superhydrophobic surface utilizes the right combination of surface chemistry and roughness that force water droplets to form high water contact angles (CA). This in turn allows droplets to easily roll off and pick up dirt and debris across the surface while also preventing water from penetrating the surface. We have developed a simple yet durable spray-on coating based on functionalized SiO2 nanoparticles that can easily be applied to surfaces including, but not limited to, optical sensors, photovoltaics, sights and lenses, textiles, construction materials, and electronic devices. In addition, these coatings exhibit practical mechanical and environmental durability that allow prolonged use of the coatings in harsh environments.
