End-functionalized starch macromolecular reagents were grafted to urethane-linked polyesters via copper-catalyzed azide alkyne cycloaddition chemistry to provide amphiphilic hybrid polymers. The starch concentration in the final graft copolymers was varied from 28-79 weight percent and the impact of starch concentration on protein repellency was studied. Quartz crystal microbalance with dissipation (QCM-D) was used to probe the interaction of these polysaccharide-containing copolymers with several proteins in a thin film mode. A general trend correlating higher starch concentrations in the graft copolymer structure with more efficient protein repellency behavior was observed. Details of both the synthesis and the QCM-D study will be presented.
