Title: DYNAMIC POLYMER HAVING HYBRIDIZED CROSS-LINKED NETWORK AND USE THEREOF
Abstract:
A dynamic polymer having hybridized cross-linked network, including common covalent cross-linking and dynamic covalent cross-linking, the dynamic covalent cross-linking being achieved by means of organic boric acid silyl ester bonds. This kind of dynamic polymer combines the respective advantages of dynamic covalent organic boric acid silyl ester bonds and ordinary covalent bonds, and a polymer having abundant structures and diverse performances can be prepared by regulating the structure of reactants. Dynamic covalent cross-linking in the dynamic polymer has strong dynamic reversibility, so that the polymer can exhibit performances such as responsiveness to stimulus, self-repair ability and the like, while the ordinary covalent cross-linking imparts the polymer a certain level of strength and stability. Further, the dynamic property of the organic boric acid silyl ester bonds can result in good energy dissipation and energy absorption effects, and increases the toughness, damping properties and impact properties by means of a specific structure. The dynamic polymer can be used to make shock absorbing cushioning materials, impact protecting materials, self-repair materials, and ductile materials and the like.
