Abstract:
Methods and solutions for fabricating a superhydrophobic, optically transparent surface on a substrate. A dip coating technique is employed in which a solution comprising hydrophobic nanoparticles, a resin binder and a solvent is provided. The substrate is dipped and then withdrawn from the solution. As the substrate is withdrawn, a precursor coating of the solution is formed on a surface of the substrate. The solvent in the precursor coating is allowed to evaporate (is otherwise removed), immediately resulting in a superhydrophobic, optically transparent coating on the substrate surface. The hydrophobic nanoparticles can be metal oxide nanoparticles (such as SiO2, ZnO, and ITO) that are surface functionalized to be hydrophobic. Substrate types include glass and polymer substrates such as PC and PMMA.
