The poor cycling stability of polyaniline (PANI) limits its practical application\nas a pseudocapacitive material due to the volume change during the charge-discharge\nprocedure. Herein, crosslinked carbon nanotubes/polyaniline (C-CNTs/PANI) composites\nhad been designed by the in situ chemical oxidative polymerization of aniline in the\npresence of cross linked carbon nanotubes (C-CNTs), which were obtained by coupling of\nthe functionalized carbon nanotubes with 1,4-benzoquinone. The composite showed a\nspecific capacitance of 294 F/g at the scan rate of 10 mV/s, and could retain 95% of its\ninitial specific capacitance after 1000 CV cycles. Such high electrochemical cycling\nstability resulting from the crosslinked skeleton of the C-CNTs makes them potential\nelectrode materials for a supercapacitor.
