Single-walled carbon nanotubes (SWNTs)-in-polymer nanofibers with a long-range ordered structure were readily produced via the electrospinning of the SWNT/polyvinyl alcohol/polyacrylonitrile solution. The resulting SWNTs-in-polymer nanofibers exhibited enhanced crystallinity due to the role of the introduced SWNTs over the process of the electrospinning followed by solidification. It was notable that the new nanostructured composite was fabricated without any special processing and treatment. Moreover, the SWNT-in-polymer nanofibers with increased crystallinity were converted to carbonized products via heat treatment under inert atmosphere. The textural properties of the carbonized products were determined by the key variables such as the nature of the polymer precursors and the content of the SWNTs introduced. Consequently, the major electrochemical properties of the carbonized products were also highly dependent on the key variables.
