Ion beam technique is a widely used, flexible and powerful tool for different materials surface engineering including polymers. High-fluence implantation of metal ions is possible tool for controlling the size and density of the metal nano-particles. The morphology of the implanted layers depends strongly on the ion fluence and the physico-chemical properties of the implanted substrates. Specimens of polyimide (PI), polyetheretherketone (PEEK), and polyethyleneterephtalate (PET) were implanted by 80 keV Co+ ions at room temperature at fluence 1.0x1016 cm–2 and annealed at temperatures below and close to Tg up to 300°C. Implanted depth profiles of as-implanted and as-annealed samples determined by RBS were compared with SRIM 2008 and TRIDYN theoretical predictions. The profiles in the as implanted samples agree reasonably with those simulated using TRIDYN code. The implanted Co atoms tend to aggregate into nano-particles, the size and distribution of which was determined from TEM micrographs and is influenced by the annealing temperature. XPS analysis was used to study chemical groups in the implanted layer of polymers. The surface morphology and roughness of ion treated polymers was determined by the AFM study. RBS and XPS results show changes of implanted depth profiles and chemical composition according to the used ion fluence and annealing temperature.
