The invention discloses a kind of dynamic aggregation objects with hybrid cross-linked network structure, wherein including dynamic covalent cross-linking and supermolecule hydrogen bond action；Wherein, the dynamic covalent cross-linking is based at least one Reversible Addition Fragmentation Chain Transfer dynamic covalent bond, and the supermolecule hydrogen bond action includes to participate in the hydrogen bond action to be formed by the side hydrogen bond group being present in the side group and/or side chain of polymer chain.The dynamic aggregation object has merged dynamic covalent bond and the respective advantage of supermolecule hydrogen bond；Supermolecule hydrogen bond assigns material stimulating responsive, ultra-tough and self-repairability；On the one hand dynamic covalent bond then assigns dynamic aggregation object structural stability and mechanical strength, and due to its dynamic reversibility, so that polymer has the characteristics such as self-repairability, recuperability, repeatable processability.The dynamic aggregation object can be used for making self-repair material, toughness material, sealing material etc. and is widely applied. |
