제목 Hydrogen-Bonded Dynamic Covalent Thiourea Motif Polymer Networks with Enhanced Reprocessability and Malleability
초록 Thiourea bonds can be included in polymer networks as a exchangable dynamic covalent linkage while bound with hydrogen bonds making it as a dual-functional motif granting a material enhanced mechanical versatility. Through manipulating the dynamic thiourea bond exchanges in our covalently cross-linked biomimetic polymer networks(BMPNs), improved malleability followed by reprocessability are exhibited yet maintaining their various mechanical properties such as stiffness, strength, toughness, resilience and adaptability. In result, BMPNs shows variable shape formability and exclusive mehcanical performances containing welding, shape reconfiguration, shape memory, load bearing, deformation/recovery, repair and reprocessing.
