Abstract :
Binary BaTiO3/PVDF nanocomposites and its nanographite (GN) doped ternary hybrids were fabricated using simple solution casting and hot compression molding. The dielectric behavior of such hybrids over a wide frequency range was studied. Additions of graphite nanosheets with their concentrations close to percolation threshold were found to be very effective to enhance the dielectric permittivity of GN/BaTiO3/PVDF nanocomposites. Furthermore, both dielectric constant and electrical conductivity of hybrids displayed strong frequency and temperature dependence.
