Conductive polymeric composites of poly(vinylidene fluoride) and carbon black modified with polyaniline were prepared via melting processing. The additivation with Eeonomers® is advantageous to the melt processing of the composites reducing the melt viscosity in comparison to the additivation with pure carbon black. The composites containing above 5%wt of Eeonomer® exhibited electrical conductivity around 10-2 S/cm, and this value remains constant even after thermal treatment at 150 ºC during 170 h room atmosphere. Differencial Scanning Calorimetry (DSC) and X-Ray diffraction analyses showed that composites containing the beta phase of PVDF could be obtained via quenching from the melt. It was also shown that the type and amount of Eeonomer® affect the crystallinity and the melting temperature of PVDF present in the composites.
