Its inertness is caused by fluorine atoms completely surrounding its carbon atoms.
Because of its dielectric properties, it is used as a material for printed circuit boards in microwave applications. Its synthesis by emulsion polymerization requires a surfactant, usually PFOA. This polymer has a coefficient of friction of less than 0.1, the lowest of any known solid, making it ideal as a lubricant. When bound to fabric fibers, it can repel stains. It is sometimes referred to by an abbreviation of its IUPAC name, PTFE, but it is most commonly known by a brand name owned by DuPont. Its inertness is caused by fluorine atoms completely surrounding its carbon atoms. For 10 points, name this material used in non-stick coatings on cookware.
