聚(3-羟基丁酸酯-co-3-羟基戊酸酯)(PHBV)是一种微生物发酵生产的热塑性聚合物。从物理、化学改性及其纤维成形两个方面综述了PHBV的研究进展。PHBV的物理改性主要有无机纳米粒子共混体系(PHBV/iNPs)、有机纳米晶共混体系(PHBV/oNPs)、高聚物共混体系(PHBV/Polymer)和绿色全降解共混体系;化学结构构筑主要包括接枝共聚改性、嵌段共聚改性、端基扩链改性等。从改性的手段及介质,分析了改性方法的优缺点。PHBV纤维的成形方法主要有熔融纺丝法、干法纺丝法及静电纺丝法。从PHBV纤维应用领域看,熔融纺纤维应用目标在于替代现有石油基相关产品,而静电纺纤维主要应用于开拓组织工程再生医学领域。最后,对PHBV今后的研究及发展提出了展望。
Poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a thermoplastic polymer produced by microbial fermentation. The research progress of PHBV was summarized from two aspects of physical and chemical modification and fiber forming. The physical modification of PHBV includes PHBV / iNPs, PHBV / oNPs, PHBV / Polymer and green degradation system. Construction of chemical structures include graft copolymerization, block copolymer modification, terminal chain extension modification. From the means of modification and medium, the advantages and disadvantages of the modified method are analyzed. PHBV fiber forming methods are melt spinning method, dry spinning method and electrospinning method. From the perspective of PHBV fiber applications, the application of melt spinning fiber aims to replace the existing petroleum-based related products, while the electrospun fibers are mainly used in the field of tissue engineering regenerative medicine. Finally, the future research and development of PHBV are put forward.
