摘要: 通过使用偏光显微镜和X射线衍射仪研究了不良溶剂的极性对利用液-液界面沉淀(LLIP)法制备的C60微纳米晶须(C60 MNWs)的光学各向异性的影响。研究结果表明:随着所用不良溶剂极性的减小,产物的光学各向异性的持久性和溶剂化结构的稳定性均先增加后减小,尤其是当使用正丁醇时,制备的C60 MNWs的该性能可达到最优。

Abstract: The effect of polarities of poor solvent on the optical anisotropy of C60 micro/nanowhiskers (C60 MNWs) prepared by liquid-liquid interface precipitation (LLIP) method was studied for the first time through the use of polarizing microscope and X-ray diffractometer. It is found that both of the optical anisotropic durability and solvated structural stability of the products increased first and then decreased by using the poor solvents with declined polarities. Especially for the use of n-butanol, the performance of prepared C60 MNWs is optimal.

Key words: C60 micro/nanowhiskers; optical anisotropy; poor solvent; solvated structures
