摘要: This contribution describes the effect of absorbing materials on functionalization and concentration radicals poly(tetrafluoroethylene) (PTFE) during γ-irradiation compared to results without materials. Different calcium-based were used study their efficiency avoid release fluorinated gases that occur within irradiation procedure in environment. It was found, type material had a significant formation functional groups (carbonyl fluoride, carboxylic acid) persistent radiation-treated PTFE samples. In addition, by means wide angle X-ray scattering (WAXS) quantitative determination fluorine (F−) after could be followed. may for scientific investigations radiation induced chain scission mechanisms as well monitoring industrial processes. © 2013 Wiley Periodicals, Inc.
