摘要
阐述了近年来生物塑料聚β羟基丁酸酯(PHB)共混改性的研究进展;介绍了PHB生物合成、化学改性和物理共混3种改性手段;分别探讨了PHB与非生物降解聚合物、可生物降解聚合物之间的共混情况,特别就共混体系的相容性、玻璃化转变温度、结晶性及机械性能进行了总结和评述;并展望了PHB材料的改性方向。
The advance of the blending modification of poly(β-hydroxybutyrate) (PHB) in recent years is reviewed,and the bio-synthesis,chemical modification and blending modification of PHB are introduced.The blending of PHB with other polymers,including bio-degradable material and non-biodegradable material,are discussed,with the emphasis on the compatibility,glass transition temperature,crystallization and mechanics properties of the blend system.Prospects for the trend of the modification of PHB are made.
