Abstract
Cobalt ferrite, Copper ferrite and cobalt doped copper ferrite nanoparticles have been synthesized and characterized using different characterization methods (XRD, FTIR and FESEM). The prepared nanoparticles have been used as promising fillers of the polyvinylidene fluoride (PVDF) polymer. The PVDF/(Cu–CoFe2O4, CoFe2O4, and CuFe2O4) nanocomposites films have been prepared via a simple solution casting technique. The optical properties and the piezoelectric response of the prepared nanocomposite films have been studied. This study showed that Cu–CoFe2O4 and CoFe2O4, have enhanced the interfacial polarization density and dielectric constant. The prepared nanofillers reduced the PVDF band gap energy value. The optical conductivity value of PVDF/(Cu–CoFe2O4 and CoFe2O4) increased five times compared with the pure PVDF. Also, an increase in the piezoelectric response has been recorded by adding the nano-fillers to the pure PVDF.
Highlights
The energy harvesting or renewable energies, such as solar energy, wind energy, vibrational energy and ocean energy, as an alternative to the traditional energy have been exploited owing to their sustainability and environment-ecofriendly [1].One of the most important energy harvesting energies is piezoelectric technology
polyvinylidene fluoride (PVDF) films were prepared by a simple solution casting technique [9] selecting dimethyl formamide (NMP) as the solvent while, CoFe2O4, CuFe2O4 and Cu-CoFe2O4 nanoparticles have been used as the fillers
Field emission scanning electron microscopy (FESEM) JEM-ARM300F operated at 200 kV was used for topographical investigation of the prepared nanoparticles
