Abstract: | Poly(aryl ether ether ketone) (PEEK) films irradiated with 2 MeV O+ and Ar+ ions to fluences in the range 1011–1013 cm?2 were treated with 5 mol/L LiCl aqueous solution at 100°C for 1 h. After removal of excessive, weakly bound LiCl the samples were annealed at temperatures from 50 to 250°C for 1 h to check the mobility of the incorporated LiCl. The amount of incorporated LiCl and its depth profile were determined using the neutron depth‐profiling (NDP) technique, which makes use of the 6Li(nth, 4He) 3H nuclear reaction. Up to the maximum annealing temperature no significant escape of the LiCl was observed. With increasing annealing temperature, a gradual migration of LiCl dopant toward the sample surface was observed on the irradiated PEEK samples. © 2002 Wiley Periodicals, Inc.
