Environment’s stuck with nonstick coatings

The family of nonstick materials that includes Teflon can degrade into pollutants that persist in the environment, new research suggests.

Known as fluoropolymers, these coatings get their tough and slippery traits from fluorine atoms strongly bonded to the materials’ carbon backbones. Manufacturers use the materials in products ranging from frying pans and other kitchen items to engines and electrical insulation.
