Construction of Impact-Resistant Polyurethane Supramolecular Elastomers with Superior Mechanical Properties Based on Quadruple Hydrogen Bonds
Polyurethane (PU) materials exhibit strong plasticity due to their unique microphase-separated structure. However, dispersing nanofiller-enhanced polyurethane elastomers remains an urgent challenge, and their impact resistance is limited. In this study, the compatibility of hydroxyapatite (HAP) with a PU matrix is im...
