Abstract

Ni[BOND]TiO2 nanoparticles were prepared by the sol–gel method, and a composite film of poly(vinylidene-trifluoroethylene) (PVDF-TrFE)/Ni[BOND]TiO2 was prepared by the solution cast method. The microstructure of Ni[BOND]TiO2 was investigated by transmission electron microscopy (TEM). The film was characterized by TEM, X-ray diffraction (XRD), differential scanning calorimetry (DSC), and dielectric property testing. The results showed that the Ni[BOND]TiO2 nanoparticles were well dispersed in the polymer matrix. With the increase of Ni[BOND]TiO2 content, the crystallinity of PVDF-TrFE/Ni[BOND]TiO2 decreased. The permittivity of the films improved significantly with the increase of Ni[BOND]TiO2 content. The permittivity at 1000 Hz and room temperature increased to 18.56 for PVDF-TrFE/Ni0.1[BOND]TiO2 (60 wt%) from the value of 11.17 for the pure PVDF-TrFE film. Furthermore, the permittivity of the composite film increased with the increase of temperature.
