摘要：

BaTiO3nanofibers of about 400 nm in diameter were synthesized via electrospinning.The evolution of the morphology and phase composition of the BaTiO3nanofibers was studied by scanning electron microscopy and X-ray diffraction within the annealing temperature of 750-1050 ℃.Higher annealing temperature led to rougher surface and better crystallization of the BaTiO3nanofibers.Below 1050 ℃,the BaTiO3nanofibers maintained its large aspect ratios and could still be regarded as individual nanofiber.The dielectric permittivities of the BaTiO3nanofibers(εr820) were calculated with the MG equation by considering the porous bulk specimens as composites of BaTiO3nanofibers and air.The ferroelectric properties of the BaTiO3nanofibers were measured by using a ferroelectric analyzer coupled with an atomic force microscope.P-E loop measured for the BaTiO3nanofiber exhibits small hysteresis.
