Hard yet Flexible Transparent Omniphobic GPOSS Coatings Modified with Perfluorinated Agents

. The fluorinated GPOSS mixtures are then photochemically cured. This study investigates the influence of the type and amount of a fluorinated agent used on the wetting and mechanical properties of the coatings. The wetting properties studied include surface energies, liquid sliding behavior, and repellency against an artificial fingerprint liquid. Meanwhile, the mechanical properties include pencil hardness, Young's modulus, hardness, and resistance to abrasion by steel wool and cheesecloth. Aside from producing coatings that may serve as a viable alternative for the currently used hard/flexible coatings in foldable smartphones, this paper provides guidelines for producing coatings with further improved omniphobicity and wear resistance.
