제목 Thiourea as a hydrogen bonding and dynamic covalent dual-functional motif for mechanical versatility in biomimetic polymer networks
초록 In this study, the use of thiourea linkage as a hydrogen bonding and dynamic covalent dual-functional motif to enhance mechanical versatility in multifaceted biomimetic polymer networks (BMPNs) are demonstrated. By controlling the dynamic thiourea dynamic covalent bond exchanges in the covalently cross-linked BMPNs, greatly improved malleability and reprocessibility are obtained while maintaining their robust mechanical characteristics of stiffness, strength, toughness, resilience, and adaptability. Such characteristics enable versatile shape manipulation and mechanical functions of the BMPN-based 3D structures, including superior shape reconfiguration, welding, shape memory, deformation, recovery, and recycling.
