Abstract
A composite article is provided which includes a blend component having first and second surfaces and a substantially non-fluorinated polymer component adhered to the first surface of the blend component, wherein the substantially non-fluorinated polymer component has an exposed surface. The blend component includes a first hydrogen containing fluoropolymer, and a substantially non-fluorinated polymer having one or more pendant primary or secondary amine groups. Increased adhesion is observed by a peel strength value between the blend component and the substantially non-fluorinated polymer component when compared to a peel strength value between a component consisting of a fluoropolymer and a component consisting of a substantially non-fluorinated polymer having pendant primary or secondary amine groups.
