摘要: Effects of inorganic nanoparticles size and thermal agitation on dielectric properties of BaTiO3/poly (vinylidene fluoride)(BT/PVDF) nanocomposite films at low frequency were studied. The dielectric properties of the BT/PVDF nanocomposite films with three kinds of diameters of BT nanoparticles loading at 50 vol.% were studied in a wide frequency range from 10− 2 Hz to 107 Hz by two measured processes. A significant low-frequency dielectric permittivity increase and the difference in dielectric properties between two measured …
