与富勒烯C_(36)直径(0.5nm)相等的碳纳米管及其制备

CARBON NANOTUBES WITH THE SAME DIAMETER AS THAT OF C_(36) (0.5nm)

在电弧放电方法制备碳纳米管中 ,通过用碳纳米管填充阳极进行放电实验 ,成功地得到了小直径单层碳纳米管 .同时在多层管的最内层得到了直径 0 5nm的碳纳米管 .这个结果表明直径小于C60 (直径 0 7nm)的碳纳米管是存在的 .

By an arc discharge technique we have grown carbon nanotubes with diameters of 0\^5nm using an anode filled with carbon nanotubes.These nanotubes are in the form of the innermost tube of multiwall nanotubes.This indicates that carbon nanotubes with diameters smaller than those of C 60 are physically possible.
