We have developed a novel synthetic method that enables us to easily synthesize metal-capsulated carbon nanotubes (CNTs) in a laboratory by using a combined technology of electrospinning-metallization and microwave heating. These techniques greatly shorten the time for the synthesis of the CNTs in comparison with the conventional methods. TEM analysis confirmed a successful formation of the CNTs, and the resulting CNTs were multi-walled and found to be about 25-100nm in diameters. The products prepared by heating at 600 and 900 degrees C exhibited less-developed and strongly curved CNTs, whereas the products prepared by heating at 700 and 800 degrees C relatively well-developed long CNTs.
