dc.description.abstract | Hydrogels with exceptional mechanical properties at high water content are crucial need for practical applications in various fields. However, achieving a hydrogel possessed splendid mechanical performance with well trade-off between tensile strength and toughness is highly demanded due to the mechanical weakness of conventional hydrogel. Herein, we report a novel kind of nanocomposite hydrogel developed by integrating chitosan decorated halloysite nanotubes (CS-f-HNTs) into dual cross-linked structure composed of chemical and Fe3+ induced ionically cross-linked network. Combining the nanoparticle reinforcement with physical interactions including hydrogen bonds among polymer chains and ionic coordination interaction between Fe3+ ions and functional groups on chitosan chains and the copolymer chains, the hydrogel exhibits extraordinary and balanced mechanical performance, including high strength (3.06 MPa), outstanding stretchability (>2000%) and superior toughness (47.6 MJ m−3) in which water content remains ~80 wt%. Based on microstructure observation and dynamic mechanical behavior analysis, we demonstrated that the addition of CS-f-HNTs effectively bridged polymer chains via physical interactions and strengthened dual cross-linked network, leading to significant improved mechanical properties. Moreover, the hydrogels also possessed remarkable self-recoverability (97.9% for small strain (200%) and 91.5% for large strain (1000%)) at room temperature and the related mechanism was discussed. The strategy developed herein may provide a newfound avenue in the design and development of strong and tough hydrogel for promising applications in loading-bearing structural materials. © 2020 Elsevier Ltd | - |
