Structure and Morphology Characteristics of Fullerene C60Nanotubes Fabricated withN-Methyl-2-pyrrolidone as a Good Solvent

摘要

Fullerene C60nanotubes (FNTs) were prepared via liquid-liquid interfacial precipitation usingN-methyl-2-pyrrolidone (NMP) as solvent and isopropyl alcohol (IPA) as precipitation agent at 8°C. C60-saturated NMP solutions were exposed to visible light to promote the growth of FNTs. Scanning electron microscopy revealed that fibers prepared in the NMP/IPA system show three different morphologies. On the basis of the different morphologies of fullerene C60nanofibers (FNFs), a possible growth mechanism to describe the formation process of FNTs is proposed.
