Abstract

Poly(vinylidenefluoride-co-hexafluoropropylene) (PVdF-HFP) nanocomposites were prepared with fluorinated barium titanate (BaTiO₃) nanoparticles. BaTiO₃ nanoparticles was treated with 2,2,2-trifluoroacetic acid in Novec-7500 and the modified surface characteristics of the nanoparticles showed good solubility in the fluorous solvent and fluorous polymer. The optimized fluorinated BaTiO₃ condition had explored by controlling temperature and ligand ratio. The prepared nanocomposite through fluorinated nanoparticles were characterized by using Fourier transform infrared spectroscopy, X-ray diffraction, impedance spectroscopy and atomic force microscopy in order to investigate their structural and electrical properties. Root mean square roughness of nanocomposites was increased only 0.48 nm after adding 20 vol.% of fluorinated BaTiO₃ nanoparticles. Also, dielectric constant of nanocomposite was predicted and agreed well with experimental data through the modified Kerner model. Dielectric constant of PVdF-HFP nanocomposite was increased about 15 thorough an addition of 20 vol.% of fluorinated BaTiO₃ nanoparticles. The application of near edge X-ray absorption fine structure spectroscopy of PVdF-HFP/fluorinated BaTiO₃ nanocomposites was presented.
