| 中文摘要 | 用丙三醇增塑玉米淀粉制备热塑性淀粉,采用熔融共混法制备了聚丁二酸丁二酯(PBS)/丙三醇增塑玉米淀粉(GTPS)复合材料。用红外光谱(FTIR)、宽角-X射线衍射(WXRD)、扫描电镜(SEM)等方法研究了复合材料的相容性、结晶性能、力学性能、微观形貌及降解性能。结果表明:加入淀粉未改变PBS的晶型;丙三醇对淀粉的塑化只发生在淀粉的非晶区;加入淀粉,PBS的拉伸强度、断裂伸长率降低,冲击强度上升;随丙三醇含量上升,体系的力学性能下降。; Biodegradable thermoplastic,poly( butylene succinate) / starch plasticized with glycerol( GTPS) blends,were prepared by Haake mixer. Compatibility,crystal structure,mechanical properties,degradable properties and microscopic morphology of the blends were investigated using FTIR,wide angle X-ray diffractometer( WXAD),scanning electron microscopy( SEM) and so on. The addition of starch would not change the crystal types of PBS. The plasticization of glycerol only occurred in the amorphous region of starch. With the addition of GTPS,the tensile strength and elongation decreased while the izod impact strengthincreased. The mechanical properties decreased with the rising of glycerol contents. |
