Electrical Properties of Binary PVDF/clay and Ternary Graphite-doped PVDF/clay Nanocomposites
Sie Chin Tjong.
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.
