对聚丁二酸丁二醇酯(PBS)薄膜在不同pH值水溶液中的降解进行对比研究。用失重率及薄膜表面形貌观察等对降解结果进行表征,结果表明:PBS薄膜在不同pH值水溶液中的降解速度为:碱性溶液>酸性溶液>中性溶液。降解过程中不同降解溶液的pH值均有一定程度的下降。
The degradation of polybutylene succinate (PBS) films in different pH aqueous solutions was compared. Degradation results were characterized by weight loss rate and surface morphology observation. The results showed that the degradation rate of PBS films in different pH aqueous solutions was: alkaline solution> acidic solution> neutral solution. During the degradation process, the pH value of different degradation solutions decreased to a certain degree.
