The influence of flowing afterglow exposure on the degradation of various polymeric materialsChanges in polymer properties which result after exposure to an atomic oxygen-rich environment of a flowing afterglow are presented. Dynamic mechanical and Fourier Transform Infrared (FTIR) spectra as well as scanning electron microscopy micrographs were employed to monitor variations in mechanical properties and chemical and physical structure. Polymers analyzed include polystyrene, PEKK, and a polyester.
