摘要

粘合剂在撞击下失效会带来巨大风险，包括财产损失、结构坍塌甚至生命损失。在此，我们通过在线性聚合物链中加入动态 B-O 链接，开发出了一系列抗冲击粘合剂。与 3 M 的商用产品相比，这些粘合剂不仅具有大面积粘合力和出色的粘合强度，而且还表现出剪切加固效应。B-O 链接提供的剪切增韧效果使粘合剂具有显著的抗冲击性，可实现 84.3%-86.3% 的力衰减效率。此外，当它们与目标材料粘合时，所产生的夹层结构仍能保持其出色的抗冲击性。因此，这类具有剪切加固效应的抗冲击粘合剂在保护精密仪器和建筑物方面具有巨大的应用潜力。

Impact-Resistant Adhesive Based on the Shear-Stiffening Effect via Dynamic B–O Linkages

The occurrence of adhesive failure under impact poses significant risks, including property damage, structural collapse, and even loss of life. Herein, we have developed a series of impact-resistant adhesives by incorporating dynamic B–O linkages into linear polymeric chains. These adhesives not only possess broad-area adhesion and superior adhesive strength compared to 3 M commercial products but also exhibit a shear-stiffening effect. The shear-stiffening effect provided by the B–O linkages endows the adhesives with remarkable impact resistance, achieving a force attenuation efficiency of 84.3–86.3%. Additionally, when they are bonded to target materials, the resulting sandwich structures retain their excellent impact resistance. Therefore, this class of impact-resistant adhesives with a shear-stiffening effect shows significant potential for applications in protecting precision instruments and buildings.
