Surperamphiphobic surfaces, exhibiting high contact angles and low contact angle hysteresis to water and low surface tension liquids,  have attracted a great deal 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 a multiscale topography that endows the surface with superamphiphobicity and repellency towards several low surface tension liguids.  Droplet impact and sandpaper abrasion tests indicate the coatings respectively possess a robust anti-wetting behavior and good mechanical durability.
