摘要：

Cupric acetate dissolved in methanol was applied, for the first time, to the synthesizing of Y-junction carbon nanotubes (CNTs). This was done by catalytic CVD of the methanol solution at 1000-1200 degrees C. Based on the bamboo structure, which was observed for the first time within Y-junction CNTs, it is suggested that the growth of such CNTs may be a result of the fluctuation of external conditions causing a change in the growth direction of CNTs developed from completely melted Cu nanoparticles. Since the production process is continuous, the present technique can easily be scaled up for large-scale production for a wide variety of applications.
