Multi-functionalization and phase separation recycling of complex crystalline polymer systems by maroscopic orientation control

对结晶/结晶聚合物共混物的相容、结晶和结构形成进行了系统的研究。我们发现，通过适当的结构控制可以调节可生物降解结晶共混物的生物降解速度。特别是在一定条件下，我们发现化学结构不同的结晶聚合物之间形成了互穿球晶。这一系列的研究已经得到了国际上的认可，我们被要求在Bankok的PPC-8上做一个主题为《可生物降解聚合物共混物的结构和性能》的主旨演讲。所研究的结晶型生物可降解聚合物有PHB、PHBVPSU、PES、PCL、PLLA、PEC及其共混物。通过原子力显微镜对体系的实时观察，证明了IPS的形成。

Systematic studies on miscibility, crystallization and structure formation of crystalline/crystalline polymer blends have been investigated. We found the speed of biodegradability of biodegradable crystalline blends can be adjusted by proper structure control. Especially, at certain condition we found the formation of interpenetrated spherulites (IPS) between chemically different crystalline polymers. The series of studies have been internationally recognized and we are aske to present akeynote lecture at PPC-8 in Bankok with the title "Structure and Properties of Bio-degradable Polymer Based Blends".The crystalline biodegradable polymers studied were PHB, PHBV, PBSU, PES, PCL, PLLA, PEC and their blends.IPS formation has been proved by real time observation of the system by atomic force microscope.
