Covalent adaptable networks (CANs) are widely used because of their outstanding mechanical properties and reprocessibility. However, these materials can only be recycled with mono-dynamic bonding networks during recovery. Here, we report that fused polymer CANs containing bi-dynamic bonds with adjustable mechanical properties are achieved through the dynamic behavior of the β-amino ester bond and the enamine-one bond. The β-amino ester bond-based CANs (P1) and the enamine-one bond-based CANs (P5) were prepared using tris(2-aminoethyl)amine (TREN) and m-xylylenediamine (MXDA) with hexanediol diacrylate and hexane-1, 6-diyl dipropiolate via click reaction, respectively. The mechanical and thermal properties of the fused films obtained after grinding and mixing at room temperature were comparable to those of CANs containing bi-dynamic bonds obtained by pre-mixing TREN and MXDA. Dynamic exchange and topological bond formation by the β-amino ester and the enamine-one at the interface are shown at the molecular level and with high uniformity. CANs containing bi-dynamic bonds showed synergism in stress relaxation experiments, demonstrating variable activation energies over a range of the temperature window. Owing to their excellent puncture resistance, the prepared materials can be used in flexible devices, energy-storage equipment, and various other applications.
