This study aims to understand the characteristics of radiation damage formed in PADC during ultraviolet (UV) irradiation, where a maximum of one molecular chain scission occurs per photon. The effects of vacuum ultraviolet (VUV) light irradiation with a wavelength of 172 nm were investigated by analyzing the reduction behavior of functional group densities using Fourier-transform infrared spectroscopy (FT-IR). Additionally, as a secondary reaction induced by VUV, ozone is generated through the dissociative excitation of oxygen molecules. In this study, VUV irradiation was performed in both atmospheric and nitrogen environments, and photochemical reactions occurring near the surface of PADC were quantitatively analyzed using FT-IR.
