<unk>  <unk>  is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The commonly known brand name of<unk> -based compositions is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938.<unk>  is a fluorocarbon solid (at room temperature), as it is a high-molecular-weight polymer consisting wholly of carbon and fluorine.<unk>  is hydrophobic: neither water nor water-containing substances wet<unk> , as fluorocarbons exhibit mitigated London dispersion forces due to the high electronegativity of fluorine.<unk>  has one of the lowest coefficients of friction of any solid.<unk>  is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant,<unk>  reduces friction, wear, and energy consumption of machinery. It is commonly used as a graft material in surgical interventions. It is also frequently employed as a coating on catheters; this interferes with the ability of bacteria and other infectious agents to adhere to catheters and cause hospital-acquired infections.
