Developing a durable multifunctional superhydrophobic coating on polymeric films that can be industrially scalable is challenge in the field of surface engineering. This article presents novel method for technology using simple single-step fabrication exhibits excellent water-repelling and UV-blocking properties, along with impressive wear resistance chemical robustness. A mixture titanium precursors, tetraethylorthosilicate (TEOS), hydrophobic silanes silica nano/micro-particles polymerized directly corona-treated film which reacts via siloxane chemistry. The then spread Mayer rod, eliminates need expensive equipment or multistep processes. incorporation nanoparticles precursor TEOS results formation silica–titania network around nanoparticles. chemically binds them to activated surface, forming unique dual-scale morphology depending size used mixture. coated were shown high water contact angle over 180° rolling 0°. due combination micro/nano roughness fluorinated hydrocarbons lowered free energy. coatings exhibited mechanical durability, as well capabilities. show remain even after sandpaper abrasion test under pressure 2.5 kPa distance 30 m.
