The need for multi-functional biomaterials has driven researchers towards more complex multi-component structures with tailor-made surface modifications. In this research, thermoset polyurethanes (tPUs) of PCL y -PEG x -PCL y , with variable block lengths, and graphene were developed and further surface-modified by Polydopamine (PDA) to improve cell adhesion. The viscoelastic and thermal proper-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
