Degradation processes in polyimide and polysulfone irradiated with energetic Kr (720 MeV) and Mo (515 MeV) ions were studied by infrared and mass spectroscopy. Most notable is the creation of alkynes, cyanates, and acetylene. The formation of such triple-bonded species within a radius of 3-4 nm arou
We have studied the carbonization of polyimide Kapton-H (pyromellitic dianhydride-oxydialinine, PMDA-ODA) thin films under heavy ion irradiations in the electronic slowing down regime. Irradiations were performed with 650-MeV Ni, 843-MeV Xe, 2.6-GeV Xe, 1.1-GeV Ta, and 707-MeV Pb ions that were tran
