Effective enhancement of dielectric properties in cold-pressed polyvinyledene fluoride/barium titanate nanocomposites

Dielectric properties of binary polyvinylidene fluoride/barium titanate nanocomposites and their nanographite doped hybrids

Binary polyvinylidene fluoride/barium titanate(PVDF/BaTiO3) and its nanographite (GN) doped ternarynanocomposites were fabricated using a simple solution casting process followed by compression molding. The dielectricbehavior of such hybrids over a wide frequency range was studied. Additions of GN with contents close to the percolationthreshold were found to be very effective to...

Investigation the Effect of Niobium Oxide Additive on the Dielectric Properties of Bismuth Titanate

Bismuth titanate ceramic has been attracted as a lead-free ferroelectric due to its high Curie temperature in high temperature applications as well as high frequency applications. In this study, the effect of niobium oxide as an additive on the microstructure and dielectric properties of bismuth titanate ceramic was investigated. For this purpose, niobium oxide was added to bismuth titanate, sy...

Magneto-dielectric properties of polymer– Fe3O4 nanocomposites

The aim of this research is to elucidate the size effect of magnetic nanoparticles on the resultant magneto-dielectric properties of polymer nanocomposites at radio frequencies. The block copolymer of [styrene-b-ethylene/butylene-b-styrene] (SEBS) was utilized as a matrix for the templating of magnetic nanoparticles. Surfactant-modified iron oxide (Fe3O4) nanoparticles of various sizes were suc...

Dielectric Properties of PE/Clay Nanocomposites

Polyethylene/nanoclay specimens containing from 0 to 5% nanoclays were prepared from a commercially available premixed PE/nanoclay masterbatch containing 50%wt of nanoclay. The masterbatch was diluted to the desired concentration by adding PE along with various amounts of compatibilizer in order to achieve the best possible dispersion of the nanoclay platelets. The dielectric response of the co...
