    Abstract

    The current paper presents an overview and analysis of data obtained on a few sets of polymer samples implanted by iron and cobalt. The low-energy (40 keV) implantations were carried out into polyimide and polyethyleneterephthalate with fluences between 2.5x10e16-1.5x10e17 cm-2. The samples were studied using several different methods to obtain information on structural and compositional changes as well as on the evolution of electrical and magnetic properties. High-fluence implantation led to significant carbonization of the polymers and formation of metal nanoparticles in the shallow layers. Correlation between the structural changes, nucleation and percolation of the particles in relation to electronic properties of the composites are found, described and analysed. A few models explaining electrical and magnetic properties of the polymer films with synthesized metal nanoparticles are suggested.
