Robust superhydrophobic coatings with micro- and nano-composite morphology

Abstract

A robust superhydrophobic coating (SC) surface can be fabricated by the sol-gel processing of long-chain 3-methacryloxypropyltrimethoxysilane and fluorosilanization by CVD. The SC surface is formed with a unique micro- and nano-composite morphology similar to that of a lotus leaf. As a result, it displays strong liquid repellency (e.g., water, brine, acidic solutions). In particular, the SC on a glass surface displays high transmission of light, robust UV durability, weather resistance, strong binding adhesion, and excellent scratch-resistant properties.
