Super-omniphobic surface prepared from a multicomponent coating of fluoro-containing polymer and silica nanoparticles

A multicomponent superomniphobic coating that can be applied to a broad range of substrates via simple spraying of a hybrid material system consisting of fluorinated poly[dimethylsiloxane-co-(3-aminopropyl) methylsiloxane (PDMS-F), fluorinated silica nanoparticles (FSiO2-NPs), and perfluoroalkyl pol...

Zusammenfassung:A multicomponent superomniphobic coating that can be applied to a broad range of substrates via simple spraying of a hybrid material system consisting of fluorinated poly[dimethylsiloxane-co-(3-aminopropyl) methylsiloxane (PDMS-F), fluorinated silica nanoparticles (FSiO2-NPs), and perfluoroalkyl polymer (F-Polymer). The PDMS-F was prepared by reacting the aminopropyl-containing copolymer of PDMS linear tridecafluoroheptanoic acid and branched heptafluoroisobutyrate respectively to yield the fluorinated polymer, named PDMS-NF and PDMS-BF respectively. By sequential spraying of PDMS-NF, FSiO2-NPs, and F-Polymer, the three-component omniphobic coating produces surface with lower contact angle hysteresis (CAH) (
