ABSTRACT: The well-de?ned core-shell carbon black/poly-
pyrrole (CB/PPy) nanocomposites were prepared via the in situ
chemical oxidative polymerization of pyrrole from the surfaces of
the carbon black (CB) nanoparticles, with poly(2-hydroxy-
3-(methacryloyloxy) propane-1-sulfonate) (PHMAS) as both
the surfactant and the dopant. The nanocomposites exhibited
the high conductivity at room temperature and the weakly
temperature dependence of conductivity from 283 to 423 K.
When the core-shell CB/PPy nanocomposites were used as the electrode materials for the supercapacitors, the maximum
discharge capacity of 366 F/g was achieved, after being corrected for the weight percentage of the PPy phase at the current density of
5 mA/cm2
in 1.0 M NaNO electrolyte solution.
