Abstract
The field of the invention relates to systems and methods for surface treatments, and more particularly to systems and methods for surface treatments, modifications or coatings using micro- and nano-structure particles for both super-hydrophobic and super-oleophobic properties. In one embodiment, a method of treating surfaces to impart both super-hydrophobic and super-oleophobic properties includes the steps of pre-treating a substrate surface; assembling dual-scale nanoparticles onto the surface of the substrate; and treating the dual-scale nanoparticle coated surface with SiCl4 to cross-link the nanoparticles to each other and to the surface of the substrate creating a robust nano-structured topographic surface having both super-hydrophobic and super-oleophobic properties.
