The microbial degradation behavior of poly(3-hydroxybutyrate--3-hydroxyhexanoate) (PHBHHx) and its compound with several polyesters such as poly(butylene adipate--telephtharate) (PBAT), poly(butylene succinate) (PBS), and polylactic acid (PLA) in seawater was tested by a biological oxygen demand (BOD) method. PHBHHx showed excellent biodegradation in seawater in this study. In addition, the biodegradation rate of several blends was much influenced by the weight ratio of PHBHHx in their blends and decreased in accordance with the decrement of PHBHHX ratio. The surface morphology of the sheet was important factor for controlling the biodegradation rate of PHBHHx-containing blends in seawater.
采用生物需氧量(BOD)法测试了聚(3-羟基丁酸酯-3-羟基己酸酯)(PHBHHx)及其与几种聚酯(如聚对苯二甲酸丁二醇酯-己二酸酯(PBAT)、聚丁二酸丁二醇酯(PBS)和聚乳酸(PLA))的共混物在海水中的微生物降解行为。在本研究中,PHBHHx 在海水中表现出优异的生物降解性。此外,几种共混物的生物降解速率受其共混物中 PHBHHx 重量比的影响很大,并随着 PHBHHx 比例的降低而降低。片材的表面形貌是控制含 PHBHHx 共混物在海水中生物降解速率的重要因素。
