| Abstract: | BaTiO3 nanofibers with different fiber diameters were synthesized by the combination of electrospinning technology and sol-gel method. The influence of concentration of electrospinning solution on fiber diameter was studied by SEM and XRD. The fiber diameter decreased with the increase of ethanol concentration in electrospinning solutions. Meanwhile,ethanol concentration in electrospinning solutions has made a great difference for the microstructure of the BaTiO3 nanofibers. |
