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
The efficacy of vacuum ultraviolet irradiation for oxidizing the surface of cellulose fibers was compared to that of the conventional wet and dry processes.
The antibacterial effectiveness of an ultravioletirradiated nylon 6,6 film was investigated for potential use as a food-packaging material to reduce the surface microbial contamination of foods. The film-surface analyses showed that UV irradiation induced conversion of surface amide groups to amines
