| 摘 要： | 利用偏光显微镜研究了乙基纤维素与聚己内酯共混物在二氯乙酸中的溶致性液晶形态。结果表明聚己内酯的分子量对共混体系的溶致性液晶结构有明显的影响。差示扫描量法测试显示含不同分子量聚己内酯的共混物，其混溶性及两组分间的相互作用无十分明显的差异。聚内酯分子量对共混体系溶致性液晶的形态和热稳定性的影响，可认为是由于分子量对体系的粘度贡献引起的。

| Abstract: | The lyotropic liquid crystal morphology of polycaprolactone(PCL)/ethyl cellulose(EC) blends in dichloroacetic acid has been studied by a polarizing light micrograph. The results indicate that the molecular weight of PCL affects the lyotropic liquid crystal textures of the blends obviously. Moreover, the results of DSC and FTIR show that the molecular weight of PCL can not affect obviously the compatibility and the interaction between PCL and EC. It can be consider that the effect of the molecular weight on the liquid crystal morphology and stability of the blends arises from the change of the viscosity in the systems. |
