A polystyrene film spun onto polished silicon substrates was implanted witheither nitrogen or argon ions using plasma immersion ion implantation (PIII)and subsequently investigated by X-ray and neutron reflectometry, UV-VIS andFTIR ellipsometry, as well as by FTIR and Raman spectroscopy. The depth profileof the densified carbon structures resulting from the ion collision cascades inthe polystyrene coating are clearly observed by both X-ray and neutronreflectometry. Argon ions produce a higher density modified layer at ashallower depth than nitrogen ions. The thickness measured for these gradedlayers agrees with the expected depths of ion implantation as calculated bySRIM. The sensitivity of X-ray and neutron reflectometry allows resolution ofdensity and hydrogen content gradients within the graphitized layers. Thetreated layers were found to covalently immobilized protein directly fromsolution. The tropoelastin protein monolayers immobilized on the surface werecharacterized. Tropoelastin remained on the surface after SDS washing.
