Abstract In this study, we present a novel strategy in which carbon dots (CDs) are employed to induce the formation of crystalline domains and further fabricated super-strong hydrogels with high crystallinity, distinct anisotropic structures dense networks based on “pinning effect”, specifically, CDs act as nanofillers heterogeneous nucleating agents. As-prepared exhibited exceptional swelling resistance, ultra-high tensile strength (156 MPa) toughness (225.2 MJ m− 3), surpassing most other tough polymers, including natural tendons, plastic, synthetic rubber artificial spider silk, etc. Notably, hydrogel can support loads up approximately 1.5×105 times its own weight, highlighting their load-bearing capacity. Moreover, be generalized adapted environments more stringent mechanical loads. This work not only offers new insights into fabricating ultra-robust but also lays foundation for design development smart materials underwater sensing.
