  2. Polytetrafluoroethylene - Wikipedia

    en.wikipedia.org/wiki/Polytetrafluoroethylene

    PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low electric polarizability of fluorine. PTFE has one of the lowest coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware.

  3. Polymer adsorption - Wikipedia

    en.wikipedia.org/wiki/Polymer_adsorption

    PTFE is a hydrophobic molecule composed of carbon and fluorine. Carbon-fluorine bonds cause PTFE to be a low-friction material, conducive in high temperature environments and resistant to stress cracking. [15] These properties cause PTFE to be non-reactive and used in a wide array of applications.

  4. Surface treatment of PTFE - Wikipedia

    en.wikipedia.org/wiki/Surface_treatment_of_PTFE

    Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.

  5. Hydrophobe - Wikipedia

    en.wikipedia.org/wiki/Hydrophobe

    The hydrophobic interaction is mostly an entropic effect originating from the disruption of the highly dynamic hydrogen bonds between molecules of liquid water by the nonpolar solute, causing the water to form a clathrate-like structure around the non-polar molecules.

  6. Thermoplastic - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic

    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 ...

  7. Non-stick surface - Wikipedia

    en.wikipedia.org/wiki/Non-stick_surface

    Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer used in various applications including non-stick coatings. Teflon is a brand of PTFE, often used as a generic term for PTFE. The metallic substrate is roughened by abrasive blasting, then sometimes electric-arc sprayed with stainless steel.

  8. Fluorocarbon - Wikipedia

    en.wikipedia.org/wiki/Fluorocarbon

    Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. [4] Its strength is a result of the electronegativity of fluorine imparting partial ionic character through partial charges on the carbon and fluorine atoms, which shorten and strengthen the bond (compared to carbon-hydrogen bonds) through favorable covalent ...

  9. Fluoropolymer - Wikipedia

    en.wikipedia.org/wiki/Fluoropolymer

    Tests showed the substance was resistant to corrosion from most acids, bases and solvents and had better high temperature stability than any other plastic. By early 1941, a crash program was making substantial quantities of PTFE for the Manhattan Project. [1] [2] [3] [4]
