Abstract
A method of forming a hydrophobic and oleophobic surface. The method including spin coating an F-POSS with 3,3-dichloro-1,1,1,2,2,-pentafluoropropane/1,3-dichloro-1,1,2,2,3-pentafluoropropane onto an inert surface. The F-POSS has a structure: Each Rf represents a nonreactive, fluorinated organic group, R1 represents a first monovalent organic group comprising at least two carbon atoms, and R2 represents hydrogen or a second monovalent organic group comprising at least two carbon atoms. The F-POSS with 3,3-dichloro-1,1,1,2,2,-pentafluoropropane/1,3-dichloro-1,1,2,2,3-pentafluoropropane are then dried on the inert surface.
