The present work was focused on studying the effects of different carbon black (CB) loadings on rheological, thermal, tensile, dynamic mechanical, and electrical properties of polyvinylidene fluoride (PVDF) and FKM composites. To these ends, dynamic mechanical analysis (DMA) was conducted, and the CB grade and method of compound preparation which was CB(N330) by melt mixing with different shear effects were examined. The composites were melting blended with CB at 190℃ in an internal mixer. After that the properties of filled and unfilled composites were compared. DMA showed the glass transition temperatures of the composites. The analysis also revealed that the area under the loss tangent (tanδ) peak decreased; moreover the tanδ temperature of the rubber phase increased by CB loading. The presence of CB improved the mechanical properties, such as Young’s modulus and tensile strength, of the composites and increased their thermal stability due to high thermal stability of CB and the interaction between CB particles and polymer matrix. The increase in the electrical conductivities of the composites under different CB loadings was also examined with different shear effects owing to different dispersion states of CB. The percolation threshold of conductive thermoplastic vulcanizate composite was observed based on conductive CB and the experimental data were well fitted to the general equation model(GEM).
