Multistage Ion Implantation of Polyamide-6 Films

The radiation defect formation accompanied by the paramagnetic centre creation by multistage boron ion implantation into polyamide-6 (PA) films was studied using the ESR technique. It was found that the multistage implantation with the energy increasing from step to step results in the rearrangement of the polymer layer being accompanied with the compensation of the terminated carbon bonds and strong exchange interaction between π-electrons. By contrast, a decrease of the ion energy from one implantation step to another one leads to the progressive accumulation of the paramagnetic centres in the implanted layers that permits to create highly conductive channels from the surface to the buried conducting carbonaceous layer produced in the polymer film via ion bombardment and to fabricate planar field-effect electronic devices based on ion-implanted polymers.
