Abstract: A high-performance triple-crosslinked polymer and a preparation method thereof are provided. The polymer is obtained by curing and cross-linking a monomer having two epoxy groups, a cross-linking monomer and a functional monomer. The polymer contains a cross-linking network formed by covalent bonds and two types of multi-level hydrogen bonds with different strengths. The interaction strength between the covalent bonds and the two types of hydrogen bonds decreases in a gradient. The dilemma of the strength-ductility tradeoff in a high-performance polymer is overcome by forming a triple-crosslinked network with covalent bonds and multi-level hydrogen bonds with different strengths in the polymer. The dynamic and hierarchical hydrogen bonds are broken and recombined timely and continuously to concurrently maintain the complete structure of the polymer network and enable the polymer network to quickly respond to the transmission and dissipation of the external environment.

Abstract: A reversible stress-responsive material, a preparation method, and a use thereof are provided. The reversible stress-responsive material prepared by the present disclosure has the property of real-time reversible force response at room temperature. When used with crosslinked plastic (high Tg) and rubber (low Tg) polymer materials, the reversible stress-responsive material can significantly enhance the mechanical strength and ductility of covalently cross-linked polymers. In the present disclosure, the triazolinedione (TAD)-indole click chemistry with the force-induced reversible property is used to construct a force-reversible crosslinked polymer material, and such a force-induced reversible crosslinking method can achieve the breakage and re-forming of covalent crosslinking points at room temperature in a solid state without any external stimuli other than the ambient temperature. This room-temperature force-induced reversible C—N covalent crosslinking can be regarded as an innovative approach to designing a high-toughness polymer material.
