中文摘要：

聚丁二酸丁二醇酯（PBS）是一种热塑性脂肪族聚酯,因力学和生物降解性等性能良好而具有广泛应用前景,但仍存在拉伸强度和生物降解速率低,成本高等缺陷,限制了其应用。通过物理改性是提高其性能和应用领域的重要研究方向之一。本文综述了近年天然高分子/PBS共混物制备和性能研究,并对天然高分子/PBS共混物的发展作了总结和展望。

英文摘要：

Due to its biodegradable,mechanical properties,poly（ butylene succinate） （ PBS） will be widely applied in the fields such as plastic,biomedical carrier or devices and so on. However,the defects in mechanical and biodegradable properties of PBS,and its high price limits the application. To increase the properties and applied fields of PBS,method such as modified PBS by physical blend was adopted. The paper reviewed the new development of the natural polymers/PBS blend, and some suggestions were de-scribed to prepare natural polymers/PBS blend with higher mechanical and thermal properties.
