Abstract Hydrogels are widely used in flexible sensing, drug delivery, and tissue engineering due to their outstanding flexibility biocompatibility, etc. However, the development of conductive hydrogels with high strength, toughness, fatigue resistance still exists significant challenges. This study introduced a novel toughening strategy based on “pinning effect”, utilizing submicron carbon cluster (CCs) unique π ‐conjugated core prepared self‐assembly acrylamide fabricate strength toughness hydrogels. The resulting CCs, coupled stress dissipation, chain entanglement, interfacial interactions polyacrylamide (PAM), effectively arrested crack propagation during stretching, thereby enhancing mechanical performance. properties PAM‐CCs significantly improved compared PAM hydrogel, showing fracture 2.33 MPa (2850% increase), an elongation ≈2400% (700% energy 126.4 kJ m −2 (3461% 14.94 MJ −3 (10571% increase). Besides, hydrogel also revealed good adhesion, compression, conductivity properties. do not require complex design or processing, using simple fast approach that showed immense potential for applications requiring
