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).


  • Fluorinating a surface or applying a fluorinated coating lowers the surface energy and makes the surface more hydrophobic. Desbief et. al. [3] coat an aluminum surface with a fluorinated block copolymer to make the aluminum more hydrophobic.
  • Lots of common pharmaceuticals are fluorinated. Fluorinating a pharmaceutical makes it more lipophilic, enhancing absorption of the drug. Some fluorinated pharmaceuticals include Prozac, Paxil, Celebrex, and Lipitor.
