摘要
介绍了聚羟基烷酸酯(PHA)的性能特点以及不足,分别探讨了PHA与天然高分子材料、人工合成高分子材料以及纳米粒子的共混改性研究进展,例如淀粉、丁酸纤维素、聚己内酯、聚碳酸丙烯酯、有机蒙脱土、碳纳米管等。并就共混体系的相容性、结晶性、机械性以及热稳定性进行了总结和评述,展望了PHA的改性方向。
The characteristic and deficiency of polyhydroxyalkanoates（PHA） were introduced. The progress on PHA modification by blending with natural polymers,artificially synthesized polymers and nanoparticles were summarized respectively, for example starch,cellulose acetate butyrate （CAB）,poly（caprolactone）（PCL）,poly（propylenecarbonate）（PPC）,organophilic montmorillonite（OMMT）,carbon nanotubes（CNT） and so on. The compatibility,crystallization,mechanical properties and thermostability of different PHA blends were reviewed. The development trend of modified PHA was prospected.
