The irradiation leads to release of hydrogen from the PEEK surface layer modified by the ion beam. The release is mild for low ion fluences but it becomes more pronounced at the ion fluences above 10(13) cm(-2). At highest ion fluences the hydrogen concentration falls to 20-35% of its initial value. In contrast to hydrogen no significant oxygen release was observed. The kinetic of the hydrogen release is similar for the three ion species. FTIR measurement shows deep structural changes of the polymer structure resulting from the ion irradiation.
