This application relates to the field of polymer materials technology, providing a PET elastomer, composite material, dynamic covalent network polymer, and its preparation method and application. The elastomer is prepared by in-situ self-assembly of crown ether-primary amide dual-functionalized PET through melt blending. Its molecular network integrates a quasi-rotaxane supramolecular crosslinking network. This structure is formed by the host-guest interaction between the crown ether and the primary amide, and can act as a sliding crosslinking point to dissipate energy through the sliding of cyclic components. This application employs a two-step end-capping-in-situ self-assembly process to overcome the technical obstacles of low PET chain-end activity and poor compatibility between polyrotaxane and PET, achieving molecular-level dispersion of quasi-rotaxane in the PET matrix. This fully utilizes the molecular pulley effect to achieve breakthrough toughening of the elastomer. Simultaneously, it combines rigid nanofillers modified with aminosilane coupling agents to form a soft-hard synergistic network, enabling the PET composite material to maintain high toughness while simultaneously improving strength, modulus, and thermal properties.
