Nylon is one of … Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene is commonly recognized under the brand name Teflon. PTFE is hydrophobic: aqueous liquids do not wet the material, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. This also supports its use in coatings of cooking ware. The polymer has one of the lowest coefficients of friction of any solid and is therefore commonly used for beari…
