Zusammenfassung:In the present research polyvinylidene fluoride was modified by loading the ceramic titanium boride (TiB 2 ) through sonication route. The structure, morphology, thermal, dielectric and softness properties were disclosed as a function of TiB 2 weight fraction composition. The decreased interplanar distance d (Å) and increased crystallinity D (Å) confirmed by X-ray diffraction technique. The C=C stretching band is shifted due to loading (wt%) of TiB 2 confirmed by Fourier transform infrared spectroscopy. Electronic structure (π–π* transition at λ = 271 nm) demonstrated the decrease in direct band gap (E g ) of nanocomposites has been confirmed by Ultraviolet–Visible spectroscopy. Optical polarizing microscopy confirms the dispersion of TiB 2 in host polymer system. The TiB 2 aggregated morphology was observed by the scanning electron microscopy (SEM). Subatomic nanoscale topography confirm the textured pattern of fillers by atomic force microscopy. The energy dispersive X-ray spectroscopy (EDXS) reveals the presence of titanium (Ti) and boron (B) elemental composition. The increased glass transition temperature (T g ), melting temperature (T m ) and thermal degradation (T d ) is due to TiB 2 weight fraction loading by thermogravimetric analysis. Dielectric constant (ε r ) increased due to loading of TiB 2 (wt%) and measured as a function of frequency and obeys the Maxwell–Wagner–Sillars interfacial polarization model. The composition of TiB 2 demonstrated the influence on decreased dissipation factor (tan δ) ultimately to control the dielectric loss relatively. The decrease in softness due to crystalline phase of nanocomposites examined by shore A durometer test. The prospectus and scope of this investigation may have headway to high charge storing multilayer capacitors and electronic applications.
