Abstract

Abstract : One‐dimensional coaxial nanofibres with a core (Ni0.5 Zn0.5 Fe2 O4 )/sheath (ZnO) were produced by coaxial electrospinning and calcining. The core/sheath structures were clearly visible by transmission electron microscopy (TEM), because of, respectively, putting chloroform and glycerin into the core and the sheath precursor solutions. Their core/sheath structures, chemical compositions and phase analysis were investigated by means of high‐resolution TEM, scanning electron microscopy and X‐ray diffraction. The results show that its mean diameter is 30 nm; the thickness of the shell is 8 nm; and ZnO promotes the axial growing of Ni0.5 Zn0.5 Fe2 O4 .
