Diffusion of silver and iodine into polymers assisted by in situ electron irradiation
Original language description
Diffusion of silver and iodine from aqueous solution into three synthetic polymers, HDPE, PI, and PEEK was studied. The samples, fully immersed in the respective chemical solution, were irradiated with 6.5 MeV electrons at room temperature to fluencies from 1.0 to 5.0 x 10(15) cm(-2). Concentration depth profiles of the diffused Ag and I atoms were determined by the RBS method. The content of the silver and iodine atoms was found to be a monotonously increasing function of the diffusion time, but it does not follow dependence expected for pure Fickian diffusion. The measured depth profiles exhibit a nearly exponential form and differ significantly from what is expected for the Fickian diffusion. Moreover, on silver depth profiles, two components are observed corresponding to particles with different mobilities. The anomalies are attributed to radiation defects created by electron irradiation, which are supposed to act as effective trapping centers for the diffusing particles. The depth
