摘要
综述了以脂肪族酯和芳香族酯为单体制备生物可降解脂肪族-芳香族共聚酯的研究进展。随脂肪族酯链段的长度和共聚酯无规立构度的变化,共聚酯的物理性能(强度、柔韧性)和降解性能发生明显的变化。这类共聚酯通常结合脂肪族聚酯的生物可降解性和芳香族聚酯优异的热和力学性能(其力学性能甚至超过低密度聚乙烯),成为一类新型可替代传统塑料的生物可降解材料,因此可推广应用于生物医学和环境友好的材料领域。
Progress on biodegradable aliphatic -aromatic copolyesters based on aliphatic and aromatic diacids, diols and ester monomers was reviewed. Physical properties and biodegradability of copolyester varied with chain length of aliphatic polyester segment and atacticity of copolyester. Aliphatic - aromatic copolyester combined excellent mechanical properties with biodegradability. Their mechanical properties were even superior to that of low density polyethylene. Therefore, aliphatic - aromatic copolyester as new type of biodegradable material would replace some general plastics in some application ,namely biomedical and environmental friendly fields.
