This paper describes a new synthesis of hyperbranched polyamine grafts on amine functionalized silicon wafers using a surface-initiated palladium-catalyzed ring-opening graft polymerization of 5-vinyl-2-oxazolidinone. The extent of grafting was followed by contact angle analysis, ATR−IR, and XPS spectroscopy. The surface mechanical properties of the resulting interfaces were characterized physically using a nanoindenter. The surface roughness of the grafts was measured using atomic force microscopy. Analogous solution-state palladium-catalyzed polymerizations of 5-vinyl-2-oxazolidinone were also investigated using isobutylamine as an initiator to provide insight into the structure of the graft polymer. |
