Structure-property-processing relationships on dual dynamic covalent adaptable networks consisting of β-amino ester and imine bonds (EI-CANs) is investigated. Various EI-CANs are prepared by adjusting the feed ratio of diacrylate and dialdehyde monomers. In general, EI-CANs with a high content of aromatic imine bonds increase glass transition temperatures and mechanical stiffness. Notably, the EI-CANs undergo the network exchange without external catalysts, enabled by both transesterification and imine. Interestingly, the accelerated stress-relaxation observed in EI-CANs compared to CANs that solely incorporate β-amino ester or imine bonds under elevated temperature. The capability of EI-CANs to undergo reprocessing under mild conditions can bring a significant benefit for preserving the intrinsic mechanical and thermal properties. Lastly, various reconfigurable shape-morphing structures are demonstrated, highlighting the potential of our materials for the development of self-expandable and reusable functional devices.
