DuPont discovers Teflon, 1938
Annoyed one day that a tank presumably full of tetrafluoroethylene gas is empty, DuPont scientist Roy Plunkett investigates and discovers that the gas had polymerized on the sides of the tank vessel. Waxy and slippery, the coating is also highly resistant to acids, bases, heat, and solvents. At first Teflon is used only in the war effort, but it later becomes a key ingredient in the manufacture of cookware, rocket nose cones, heart pacemakers, space suits, and artificial limbs and joints.
