Structural, mechanical, and biocompatibility analyses of a novel dental restorative nanocomposite

Structure and biocompatibility are key parameters that determine the usefulness of dental materials for clinical use. Novel polyurethane (PU) nanocomposite material was prepared by chemically binding nanohydroxyapatite (nHA) to the diisocyanate component of the PU backbone by solvent‐polymerization. nHA was incorporated into PU by the stepwise addition of monomeric units of the PU. The PU/nHA composite was analyzed by 13 C Nuclear magnetic...
