Abstract
Method of making a oleophobic layer on a fluoropolymer (e.g., polytetrafluoroethylene (PTFE)). The oleophobic layer includes a fluoroalkyl acrylate copolymer. The fluoropolymer may be an expanded PTFE formed into a porous membrane. The oleophobicity may be sufficient to repel #8 oil (n-heptane) in accordance with AATCC Test Method 118. There are also coated articles including fluoropolymers and oleophobic layers made from fluoroalkyl acrylate copolymers.
