Polyimide (PI), polyetheretherketone (PEEK) and polyethyleneterephthalate (PET) were implanted with 40 keV Ni+ ions at room temperature using different fluences. The samples were then annealed at different temperatures close to the glassy transition temperature. The depth profiles of the Ni atoms were determined by the RBS method. The surface morphology of the implanted polymers was studied using AFM. The size and distribution of the Ni nanoparticles created in the polymer surface layer were determined using TEM. In the case of PET, the annealing results in a significant redistribution of the Ni atom-particles towards the sample depth. According to the TEM observation on the PI as well as the as-implanted PET and PEEK samples, the diameter of the Ni nanoparticles increases with increasing ion fluence. Subsequent annealing leads to a slight reduction in the nanoparticle diameter depending on the polymer type. With increasing annealing temperature, the surface morphology changes.
