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 or applying a fluorinated coating to a surface lowers the surface energy and makes the surface more hydrophobic. Desbief et. al. [3] coat an aluminum surface with fluorinated block copolymers to make the aluminum more hydrophobic.
  • Lots of common pharmaceuticals are fluorinated. Fluorinating a pharmaceutical makes it more lipophilic, enhancing absorption of the drug [4]. Common fluorinated pharmaceuticals include Prozac, Paxil, Celebrex, and Lipitor [5]. The pros and cons of fluorinated drugs and their effects on the environment are a topic of debate.
