Nanofiber web of MnFe2O4 with diameters of 100 – 400 nm were prepared by calcining electrospun nanofiber of poly(vinyl acetate) (PVAc) / manganese–ferrite precusor composite solution. These PVAc / manganese–ferrite hybrid nanofiber were obtained from a homogenous solution of PVAc with a sol–gel of Manganese (Ⅱ) nitrate and Iron (Ⅲ) nitrate Enneahydrate by using the electrospinning method. The nanofiber webs were characterized by SEM, XRD and FT-IR. SEM, XRD and FT-IR results indicated that the morphology and crystalline phase of MnFe2O4 nanofiberes were strongly influenced by the calcination temperature. |
