Abstract
Polyimide (PI) foils were implanted with 40 keV Fe+ and Co+ ions to the fluences of 2.5x10e16-1.25x10e17 cm-2 at the ion current densities of 4, 8 and 12 microA.cm-2. Surface morphology and compositional alteration of the implanted polymer have been studied using atomic force microscopy (AFM), transmission electron microscopy (TEM), Rutherford back-scattering (RBS) and X-ray photoelectron spectroscopy (XPS). Carbonisation of the surface layer, followed by oxygen and nitrogen depletion is observed. These processes reach the saturation level at the applied high fluences. A further increase of ion fluence and density of ion current does not change the composition; only an increase in the metal concentration is observed. It is shown that metal ion-implantation to high fluence at high ion current density can be effectively employed to form metal/polymer nanocomposites with required parameters.
