The polyethylene (PE) films implanted with B+ and Ar+ ions with fluences of 1x10e13 - 1x10e17 cm-2 and diffusive doped from aqueous solution of FeCl3 are studied. It was found that the subsequent FeCl3 diffusion influences slightly the paramagnetic properties of the implanted polymer films that evidence about weak chemical interaction of the dopants with the free radicals and radiation defects. The FeCl3 doping of the ion implanted PE results in an increase of the surface layer conductivity and does not influence the conductivity of the buried carbonaceous layer created by high fluence implantation. The surface conductivity increase is caused probably by the additional mechanisms of the charge carrier transport due to the interaction of the dopants with π- and OH−-radicals. The weak effect of the dopants on the electrical parameters of the buried carbonaceous layer is caused by the compensation of unsaturated bonds and free radicals in the layer.
