The large difference in the electrical conductivity between insulating polymers and highly conductive nanomaterials is believed to be responsible for strong interfacial polarization in conductive polymer nanocomposites. Thus, the extremely high dielectric permittivity has been frequently achieved in conductive polymer nanocomposites compared with ceramic-modified polymer nanocomposites [9-24]. Figure 4.1 presents one of the highest dielectric permittivity . In this study, exfoliated graphite nanoplates were incorporated in PVDF matrix. The resulting nanocomposites showed very uniform dispersion of nanoplates, leading to very high dielectric permittivity in the entire frequency range.
