| Abstract: | A method is described for obtaining a composite of polyaniline and carbon black by cycling the potential of a Pt electrode in a solution containing aniline and carbon black suspension. The solution may also contain sodium dodecyl sulphate (SDS) as additive. It is shown that the rate of polymerization is enhanced by the presence of both carbon black and SDS by a factor of 5. The composite was characterized by cyclic voltammetry, scanning electron microscopy and capacity measurements. |
