Dielectric properties of Poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) based composites with surface hydroxylated BiFeO3 (h-BFO) particles were prepared by solution casting techniques. The h-BFO fillers were synthesized from BiFeO3 in aqueous solution of H2O2. The result showed that the dielectric properties of the h-BFO-PVDF-HFP composite exhibits better dielectric properties than that of the unmodified BFO-PVDF-HFP composites. Meanwhile, the 30 wt% of h-BFO-PVDF-HFP composite showed higher dielectric constant, better suppressed dielectric loss, high remnant polarization and high electrical conductivity. It is suggested that the strong interaction between h-BFO particl...
