Superhydrophobic and Oleophobic Functional Coatings Comprised of Grafted Crystalline Polymers Comprising Perfluoroalkyl Moieties

摘要

Described herein are methods of preparing superhydrophobic and oleophobic surfaces by grafting poly(perfluoroalkyl acrylate) chains on silicon substrates with initiated chemical vapor deposition. The grafting enhances the formation of the crystalline phase. The crystalline structures reduce the polymer chain mobility, resulting in nonwetting surfaces with respect to both water and mineral oil.
