On This Day in Inventor History: The Birth of Teflon On February 4, 1941, chemist Roy J. Plunkett received a patent for tetrafluoroethylene polymers, better known as Teflon. This remarkable material has since become integral to various industries, from non-stick cookware to aerospace applications. In 1938, while working at DuPont's Jackson Laboratory in New Jersey, Plunkett was experimenting with gases related to refrigerants. During one experiment, a gas called tetrafluoroethylene (TFE) was stored in cylinders at low temperatures. Upon opening one cylinder, Plunkett discovered that the gas had unexpectedly polymerized into a white, waxy solid. This serendipitous discovery led to the development of a material with unique properties: it was extremely slippery, chemically inert, and had a high melting point. Recognizing its potential, DuPont trademarked the polymer as Teflon in 1945. Initially, Teflon was utilized in military and industrial applications, such as coating valves and seals in the Manhattan Project due to its resistance to corrosion. By the 1960s, Teflon had entered households as a non-stick coating for cookware, revolutionizing the culinary world. Plunkett's accidental discovery underscores the importance of curiosity and openness to unexpected results in the inventive process. His work exemplifies how unforeseen outcomes can lead to groundbreaking innovations that transform everyday life. Primary Source: U.S. Patent No. 2,230,654 – Roy J.
