Definition

Fluorination is the chemical process of adding the element fluorine into a molecule. Fluorine has atomic number 9 and is in group 17, the halogens. Fluorination is a kind of halogenation. This periodic table is from wikimedia commons and shows Fluorine's position at the top of the Halogens (group 17).

Applications

  • Fluorinating a surface or applying a fluorinated coating lowers the surface energy and makes the surface more hydrophobic. Desbief et. al. [3] discuss this idea in terms of polymer coatings, "introduction of fluorine atoms substantially reduces the surface energy of the polymer film."
  • Pharmaceuticals
