Parylene (poly-p-xylylene), and its family of halogenated variants, have a long history for application as protective coatings and dielectric barriers. Among them, Parylene-C is the most popular due to its high impermeability to moisture, resistance to corrosive environments, and its vapor deposition polymerization, which is self-initiated and unterminated creating an extremely pure polymer coating. Here, in order to apply these advantageous material characteristics in an environment containing ionizing radiation the effects of irradiation on the chemical stability of the polymer throughout the lifetime of the material needs to be further understood.
