摘 要: 聚碳酸亚丙酯(PPC)是一种新型脂肪族聚碳酸酯,具有良好的生物相容性、降解性和极低的氧透过率,但其热性能和机械强度较差。聚碳酸亚丙酯的共混改性可以有效改善其性能。综述了近年来国内外聚碳酸亚丙酯共混改性的研究情况,分别介绍了聚碳酸亚丙酯/合成聚合物、聚碳酸亚丙酯/天然聚合物、聚碳酸亚丙酯/无机粒子、聚碳酸亚丙酯/有机小分子复合材料的制备方法与性能,并展望了其发展前景。 Poly(propylene carbonate) (PPC), a new kind of aliphatic polycarbonate, has attracted much atten- tion owing to its good properties, such as biocompatibility, biodegradability and abnormally low permeability toward oxygen. However, its high cost, poor thermal performance and mechanical properties, hinder its commercial applica- tion on a large scale. Blending modification is an effective way to improve the performance of PPC, therefore, the re- cent progress in blending modification of PPC with synthetic polymers, natural polymers, inorganic particles and or- ganic compounds are reviewed.
