摘要: The surface properties of the polyethylene (PE), polypropylene (PP) and polystyrene (PS) samples doped with 150 keV F+ ions doses 1 × 1012-1 1015 cm–2 have been characterized by different techniques their biocompatibility to vascular smooth muscle cells was examined. concentration conjugation length double bonds produced ion impact, conductivity polarity increased level doping. cell density measured on PP PS below 1013 cm–2. cultured ion-doped exhibited better homogeneity resulting several times higher than that undoped polymers. No such effects were observed PE. enhanced proliferation correlates
