Composites containing the f3.,phase of PVDF tive additive made via in situ deposition of polyaniline oro could be obtained via quenching from the melt, as indicated polypyrrole on carbon black particles were produced by a by X-Ray diffraction analysis. The type and amount of the melting process. Electrical conductivity in the arder of 10-2 S/cm could be achieved with low contents of the conductive fillerr. Thermogravimetric analysis (TGA) showed that there is no appreciable degradation of the composites at temper- atures as high as 300°C. Moreover, the addition of the conducting polymer-modified carbon black additive is advantageous to the melt processing of the composites, reducing the melt viscosity in comparison to the addition of pure carbon black. aCristalização aAditivos aCompostos aProcesso de fusão1 aAVLYANOV, J.1 aGREGORIO JR.
