摘　　要：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） as a kind of thermoplastic bio-polymer synthesized by microbial fermentation, presents the advantages of good biodegradability, bistocompatibility, etc. The recent research developments of PHBV were introduced from physical, chemical modification and its fiber forming. The physical modification of PHBV are composed of PHBV/inorganics nanocomposites, PHBV/organics nanocomposites, PHBV/ petroleum-based polymer composites and fully bio-degradable composites, while the chemical modification was proceeded by graft modification, block modification and copolymerization modification. The advantages and disadvantages of modified PHBV have been compared and discussed from the modified methods and medium. The fiber formation of modified PHBV are mainly processed by melt spinning, dry spinning and electrospinning method. The melt spun PHBV fibers will be targeted to substitute some of the synthetic petroieum-based fibers like PP, PET fibers, while electrostrun PHBV fibers will be successfully and widely used in the field of tissue engineering and regenerative medicines. Moreover, the further research and development direction of PHBV were also presented.
