- Fluorinating or applying a fluorinated coating to a surface lowers the surface energy and makes the surface more hydrophobic. Desbief et. al.  coat an aluminum surface with fluorinated block copolymers to make the aluminum more hydrophobic.
- Many companies make fluorinated plastic containers that are less permeable than plain HDPE containers.
- Lots of common pharmaceuticals are fluorinated. Fluorinating a pharmaceutical makes it more lipophilic, enhancing absorption of the drug . Common fluorinated pharmaceuticals include Prozac, Paxil, Celebrex, and Lipitor . The pros and cons of fluorinated drugs and their effects on the environment are a topic of debate.
