Abstract
A hydrophobic and oleophobic coating composition includes at least a polysilazane polymer, a fluoroacrylate copolymer, and a thermosetting fluorinated polymer. The coating composition can be applied to a substrate in a single-step process as a thick and durable polymeric layer. Methods for making the coating composition and related articles are also provided.
