Abstract
Silicone (polydimethylsiloxane) sheets and tubes were irradiated with Ar ions using plasma-based ion implantation (PBII). The roughness of the surface increased dramatically with increasing applied high voltage. The Raman spectra showed a destruction of methyl groups and the formation of amorphous carbon structures. The RBS measurements indicated an enrichment of carbon atoms and the presence of implanted ions at the surface. Owing to the irradiation, the adhesive strength of the fibrin glue (a biological tissue adhesive) improved from 0.08 to 0.57 N/mm2 and the cell attachment percentage increased from 50 to 85% in a sample irradiated at 5 kV.
