报道了高性能可回收交联聚合物的仿生分子设计和合成。通过马来酰亚胺悬垂基团与呋喃交联剂之间的diols - alder反应，将硬段之间的可逆交联纳入线性分段聚氨酯。该材料具有层次化结构，具有较高的刚度、强度和韧性，且易于热重塑和再修补。
Bio-inspired molecular design and synthesis of high-performance and recyclable cross-linked polymers is reported. Reversible cross-links between hard segments are incorporated into linear segmented polyurethane via Diels-Alder reaction between maleimide pendant group and furan cross-linker. The materials form hierarchical structure and exhibit excellent properties with high stiffness, strength and toughness, and can be easily thermally reshaped and re-mended.
