    Abstract

    Short multiwall carbon nanotubes (MWCNTs) were synthesized by pyrolysis of a polysilazane-polyvinyl pyrrolidone mixture that was characterized by dynamic light scattering. It was found that the polymer mixture had a tube-shaped Aggregate at the nanometer scale. The MWCNTs are similar to 30 nm in diameter and similar to 500 nm in length. Structural characterization revealed that they have a well-developed tubular structure with a uniform wall thickness, but are not well graphitized. The formation of the MWCNTs can be accounted for by the self-assembly of polyvinyl pyrrolidone in the solution to form polymeric nanotubes. that were converted to MWCNTs by subsequent pyrolysis.
