用扫描电镜和透射电镜分析了直径在亚微米和微米之间的C-60和C-70晶须的结构。富勒烯晶须是通过富勒烯甲苯溶液与异丙醇形成液-液界面而制备的。观察到C-70晶须的生长前沿是结晶的。假设C-70晶须处于有序-无序转变状态。C-60晶须具有很强的柔韧性，弯曲后的C-60晶须被切割成更细的C-70晶须。C-70晶须显示出较高的结晶度，但在C-60晶须中观察到高密度的位错。
The structure of C-60 and C-70 whiskers with diameters between submicrometers and micrometers were analyzed by scanning electron microscopy and transmission electron microscopy. The fullerene whiskers were produced by forming liquid-liquid interfaces between toluene solutions of fullerenes and isopropyl alcohol. The growth fronts of C-70 whiskers were observed to be crystalline. The C-70 whiskers were assumed to be in a state of order-disorder transition. The whiskers of C-60 are very flexible, and C-60 whiskers bent strongly were tom into finer C-70 whiskers. The C-70 whiskers showed a higher crystallinity, though a high density of dislocations was observed in the C-60 whiskers.
