Introduction of Fluorine and Fluorine‐Containing Functional Groups [PDF]
Angewandte Chemie International Edition, 2013 AbstractOver the past decade, the most significant, conceptual advances in the field of fluorination were enabled most prominently by organo‐ and transition‐metal catalysis. The most challenging transformation remains the formation of the parent CF bond, primarily as a consequence of the high hydration energy of fluoride, strong metal—fluorine bonds ...

Surface modification of polyethylene terephthalate films by direct fluorination
AIP Advances, 2018 Polyethylene terephthalate (PET) films were surface fluorinated in a reaction kettle using a F2/N2 blend with 12.5% F2 by volume for the different time of 15, 30, 60, and 90 min at the same temperature of 30 °C.
