The intrinsic compromise between strength and toughness in composite epoxy resins significantly constrains their practical applications. In this study, a novel strategy is introduced, leveraging interfacial π-π stacking interactions to induce the "rolling behavior" of microsphere fillers, thereby facilitating efficient energy dissipation. This approach corroborated through theoretical simulations experimental validation. resulting resin demonstrates an impressive 49.8% enhancement remarkable 358.9% improvement compared conventional resins, accompanied by substantially reduced hysteresis. Moreover, system achieves reversible closed-loop recyclability rapid repair capabilities. preliminary demonstration "force-temperature equivalence" further establishes pathway for design high-performance materials.

In conventional double network (CDN) hydrogels, dense chemical cross-linking in the first frequently induces structural imperfections, resulting significant energy dissipation and substantial hysteresis under stress. To improve uniformity, spatial heterogeneities can be minimized by introducing mobile cross-linking, which facilitates creation of a more homogeneous network. Herein, we employed polymerization-induced entanglements (PIEs) strategy to tune from traditional net-like fabric-inspired topology, simultaneously promoting greater chain entanglement with second This innovative approach enables PIEs DN hydrogels exceptional performance, including significantly reduced (0.15), high tensile strength (1.25 MPa), excellent toughness (5800 J/m2), overcoming long-standing trade-off between observed CDN offering insights avenues for expanding hydrogel applications.
