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时降解结果进行表征,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 rates of poly ( butylenes succinate) (PBS) films were compared in aqueous solution with different pH values. The experimental results were characterized by weight loss rate and the observation of surface morphology. The results indicated that the degradation rates of PBS films in aqueous solution on different pH values reduced as follows; alkaline solution > acidic solution > neutral solution. The pH values of various degradation aqueous solutions decreased in different degrees.
