Nitrogen-doped carbon fibers and membranes by carbonization of electrospun poly(ionic liquid)s

Poly(ionic liquid)s with well-defined chemical structure were prepared and applied as precursors for nitrogen-doped carbon fibers and membranes via the electrospinning technique. The nitrogen contents of two prepared carbon membranes were found to be 6.3% and 8.0% respectively. Their electrical conductivity was measured to be ca. 200 S cm(-1).
