Annotation: Ion implantation is one of the most effective and promising methods for the material surface property modification, such as surface resistivity. In this study the silver and carbon ion implantation with doses of 1·10 14 , 1·10 15 , 1·10 16 ions/cm 2 effect on polytetrafluoroethylene (PTFE) and polylactide (PL) surface resistance alteration has been investigated. It was found that the implantation of silver ions with energy of 40 keV and carbon with energy of 20 keV reduces the surface resistivity of polylactide by 3–5 orders of magnitude and PTFE by 1 order of magnitude.
