Electrical Properties of Binary PVDF/clay and Ternary Graphite-doped PVDF/clay Nanocomposites
Functional polyvinylidene fluoride based composites filled with two-dimensional clay platelets and graphite nanosheets were prepared by means of solution mixing process. The dielectric responses of binary PVDF-clay and ternary graphite doped PVDF-clay nanocomposites were determined
using broad band AC impedance spectroscopy. The results showed that the clay additions enhance permittivity of PVDF due to the formation of beta-phase polymorph. The permittivity of PVDF-clay nanocomposites can be further increased by adding conductive graphite nanosheet (GN). The hybrid composite
with 3 wt% GN exhibited dielectric permittivity of 195 and low tangent loss of 0.45.
