Abstract
A surface can be coated with a liquid repellent coating. Materials for making the liquid repellent coating (e.g., a fingerprint resistant coating) can be selected on the basis of surface energy considerations, such as a receding surface energy. The materials can include a polymer and a liquid repelling material, for example, poly(ethyl methacrylate) and a fluorinated silsesquioxane such as fluorodecyl POSS.
Claims10
A method of making a liquid repellent coating on a non-porous surface, the method comprising:
- combining a fluoropolymer with a polymer, the polymer being poly(ethyl methacrylate), poly(butyl methacrylate), or both, to form a mixture;
- and
- applying the mixture to the non-porous surface to form a coating thereon, the coating being hydrophobic and oleophobic.
