聚甲基乙撑碳酸酯/天然高分子复合材料研究进展

A review of the blend of poly( propylene carbonate) /natural polymers

聚甲基乙撑碳酸酯(PPC)是一种新型热塑性脂肪族聚碳酸酯,具有良好的生物降解性、高阻隔性和生物相容性等优点,但其热性能和力学性能较差,通过物理和化学方法改性是提高其性能的重要研究方向之一。本文综述了近年来采用淀粉、纤维素和甲壳素等天然高分子对PPC的改性研究,尤其是天然高分子含量和预处理方法等对复合材料性能的影响,并对PPC/天然高分子复合材料的发展作了总结和展望。

Due to its thermoplastic, superior biodegradable, high barrier property and biocom-patibility properties, Poly （ propylene carbonate） （PPC）is widely applied in the fields such as plastic, medicine and so on. Unfortunately, the thermal and mechanical properties of PPC are poor. To resolve these problems, a method is blended the PPC with natural polymers such as starch, cellulose and chitin. The paper reviews the new development of the PPC/natural polymers blend, and some suggestions are described to prepare PPC/natural polymers blend with higher mechanical and thermal properties.
