Abstract

Superamphiphobic surfaces, exhibiting high contact angles and low contact angle hysteresis to both water and low surface tension liquids, have attracted a great deal of attention in recent years due to the importance in many practical applications. In this work, we present a simple strategy for fabrication of superamphiphobic coatings based on photopolymerization of hybrid thiol-ene resins. Spray-deposition and UV cure of thiol-ene resins containing hydrophobic silica nanoparticles and fluorinated thiols provides multi-scale topography and low-energy surface that endows the surface with superamphiphobicity and repellency towards several low surface tension liquids. Droplet impact and sandpaper abrasion tests indicate the coatings respectively possess a robust anti-wetting behavior and good mechanical durability.
