| Abstract |
We report significantly enhanced dielectric permittivity and suppressed dielectric loss in Na1/2Bi1/2Cu3Ti4O12/
poly(vinylidene fluoride) (NBCTO/PVDF) nanocomposites. NBCTO nanoparticles (≈100 nm) synthesized via a chemical combustion method were used as a filler to enhance the dielectric permittivity of PVDF polymer. NBCTO/PVDF nanocomposites with various volume fractions of NBCTO were fabricated using conventional mixed powders and hot pressing. Microstructural analysis revealed good dispersion of NBCTO nanoparticles in the PVDF matrix compared to that of NBCTO micro-particles. The dielectric permittivity of NBCTO/PVDF nanocomposites increased with increasing NBCTO filler content. Interestingly, at 103 Hz, the nanocomposite with
50 vol% of NBCTO exhibited a largely enhanced dielectric permittivity of about 261 and a low dielectric loss of 0.4. Greatly increased dielectric permittivity in the NBCTO/PVDF nanocomposites can be ascribed to large interfacial spaces and short interparticle distances. |
