Paper Abstract

A superhydrophobic (SH) surface has many characteristics, one of which is its self-cleaning, anti-soiling functionality, that are desirable across various industries. A transparent, self-cleaning 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. In theory this is simple but in practice this can be very difficult as superhydrophobicity and optical transparency are competitive. We have developed a simple, spray-on coating based on functionalized SiO2 nanoparticles that can easily be applied to surfaces whose application requires high transparency including, but not limited to, optical sensors, photovoltaics, sights, and lenses. In addition, these coatings exhibit practical mechanical and environmental durability that allow prolonged use of the coatings in harsh environments.
