In both natural and artificial functional systems, the cooperation between different dynamic interactions is of vital importance for realizing complicated functions. Dynamic covalent bonds are one kind of relatively stable dynamic interactions and have shown synergistic effect in natural systems such as functional proteins. However, synergistic interactions between different dynamic covalent bonds in polymeric materials are still unclear. Herein, polymeric materials containing diselenide and imine bonds are prepared, and then the synergistic effect between the two dynamic covalent bonds is quantitatively evaluated in typical processes of dynamic materials. The results reveal that dynamic covalent bonds show weak synergistic effect in the degradation process and have strong synergistic effect in stress relaxation process. Therefore, introducing multiple dynamic covalent bonds in polymeric materials can extensively enhance their dynamic properties.

当动态二硒键与高分子材料中的动态亚胺键相遇时

在自然功能系统和人工功能系统中，不同动态相互作用之间的协作对于实现复杂功能至关重要。动态共价键是一种相对稳定的动态相互作用，在功能性蛋白质等自然系统中表现出协同作用。然而，聚合物材料中不同动态共价键之间的协同作用仍不清楚。在此，制备了含有二硒键和亚胺键的聚合物材料，然后在动态材料的典型过程中定量评估了两个动态共价键之间的协同效应。结果表明，动态共价键在降解过程中的协同作用较弱，在应力松弛过程中的协同作用较强。所以，
