Degradation of thin films of a fluoropolymer

Abstract
1H‐1H‐Pentadecafluorooctyl methacrylate, a fluoropolymer, is used as a barrier coating to control spreading of thin liquid films, notably silicone oil. Using infrared spectroscopy and thermogravimetric analysis, this work describes the thermal degradation of thin films of this fluoropolymer. The conclusions are that the degradation is a two‐stage, thermal bond‐breaking phenomenon which does not required an additional reactant such as oxygen or water vapor. Rate constant data are presented for both stages of the degradation.
