聚酯的生物改性

Biological Modifacation of Polyesters

从四个方面综述了近年来聚对苯二甲酸乙二酯(PET)和聚对苯二甲酸丁二酯(PBT)生物改性的研究进展:(1)在聚酯合成中采用生物原料;(2)采用共聚技术制备可生物降解性共聚酯;(3)生物活性物质在聚酯中的引入改性,可提高其生物相容性和抗菌能力,在聚酯用于人造器官时,可使血管纤维原细胞的细胞增殖;(4)生物酶对聚酯进行水解改性,可减轻重量,并改善吸湿性、染色性等性能。

In this paper the research works of biological modification of poly(ethylene terephthalate)(PET) and poly(butylenes terephthalate)(PBT) are reviewed:(1)Preparation of biological raw materials and using biological raw materials in process of synthesis of polyesters;(2)Synthesis of biodegradable aliphatic-PET(PBT) copolyesters;(3)Immobilization with biologically active components into PET fiber and film,the antibacterial activity of PET is increased and the fibroblast proliferation can be promoted to a high p...
