摘要

This paper aims to test polyurethane-metal oxide composites, to improve image quality resulting from MRI investigations. A polyurethane based on PTMEG-Pluronic L-31, MDI extended with BD and PDMS was studied. Thus, polyurethane-based composites (PUC) mixed with different quantities of iron oxide nanoparticles (IONp) were obtained, marking the electromagnetic properties of the resulting materials. A cytotoxicity study of these composites was also performed.
