Enhanced dielectric and electrical properties of tri-phase percolative PVDF–BiFeO3–Carbon Black (CB) composite film

A tri-phase polymer composite film with a multiferroic phase (BiFeO 3 ) and conductive carbon black (CB) deposited on the BiFeO 3 (BF) and poly(vinylidene fluoride) (PVDF) matrix were prepared by using a solution casting technique. The dielectric and electrical performance of BF–PVDF composites with...

Zusammenfassung:A tri-phase polymer composite film with a multiferroic phase (BiFeO 3 ) and conductive carbon black (CB) deposited on the BiFeO 3 (BF) and poly(vinylidene fluoride) (PVDF) matrix were prepared by using a solution casting technique. The dielectric and electrical performance of BF–PVDF composites with various weight percentages of CB content was studied. It has been observed that the incorporation of high loading of CB to the BF–PVDF composite system led to a significant improvement in the dielectric constant with suppressed dielectric loss (
