| 中文摘要: |
| 目的 综述近年来国内外聚（3-羟基丁酸酯-co-3-羟基戊酸酯）（PHBV）的改性研究进展，为进一步开发PHBV在包装领域的应用提供科学的理论基础。方法 以PHBV薄膜材料为主，根据PHBV的优缺点，从物理改性和化学改性2个方面进行阐述。结果 PHBV是一种拥有生物可降解性的热塑性树脂，具有广阔的应用前景，但PHBV的脆性大、韧性差，必须对其进行改性，且物理和化学改性均有优缺点。结论 大量研究表明，PHBV经过改性后性能有所改善，但由于其相容性差导致复合材料性能的提升幅度有限，因此，有待开发和完善PHBV的生物降解性，且工艺简单、成本又低的改性技术。 |

| The work aims to review the research progress of poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) modification at home and abroad in recent years to provide a scientific theoretical basis for the further development of PHBV application in the packaging field. Based on the advantages and disadvantages of PHBV film materials, the physical and chemical modification of PHBV were discussed. PHBV was a kind of thermoplastic resin with biodegradability and had broad application prospects. However, PHBV had high brittleness and poor toughness, and must be modified and both physical and chemical modification had advantages and disadvantages. Numerous studies have shown that the properties of PHBV have improved after modification, but the performance of composites is limited due to poor compatibility. Therefore, it is necessary to develop and improve modification technology that does not sacrifice biodegradability of materials but has simple process, and low cost. |
