ULTRA HYDROPHOBIC SURFACE FABRICATED ON TOLE SUBSTRATE

Abstract

The functional surface is a new concept, which refers to the modification Physical-Chemical properties to equip surface with properties that the original material cannot have such as anti-wetting, anti-reflection, avoiding the deposition of substances, anti-ice, etc. However, the fabrication process requires complicated, expensive, and time-consuming technologies for further applications. This study presents a cheap and facile method to fabricate the functional surface on Tole substrate for water repellent and dust removal application. Bare Tole substrate was initially ground using sandpaper to generate the microscale structures and followed by the wet etching method using an acid solution to create the hierarchical structure. The treatment process was followed by the chemical compound coating to ensure the hydrophobicity of the rough surface. After being treated, the surface introduced a complete hydrophobicity, and anti-fouling properties and can be observed by a high-speed camera. The research results will suggest solutions for the fabrication of functional surfaces oriented to outdoor applications.
