【Abstract】 The sources and types of bio-based monomers for bio-based polyester elastomer(BPE), as well as the structure and properties of BPE, were introduced. The primary fabrication techniques for BPE-based blends or composites, including melt blending, solution blending, in-situ polymerization, were comprehensively elucidated. Furthermore, the notable advantages of BPE and its composites were critically analyzed with respect to environmental friendliness and sustainability, tunable physicochemical performances, mechanical properties, and cross-domain applications. A systematic summary was provided on the current application status and future potential of BPE and its composites in key industrial sectors such as automotive materials, electronic devices, 3D printing, and medical materials. Finally, the existing challenges faced by BPE materials in terms of the development of bio-based monomer types, molecular structure and performance regulation, cost control, and processing stability were discussed, and the future development direction of BPE materials was prospected.更多还原
