Electrospinning is a directly method to produce polymer fibers from polymer solution with diameters in the range of sub-micron. In this study, PVAc solutions with different amount FeSO4·7H2O were prepared by using the mixture of methanol, ethanol and N,N-dimethyl foramide(DMF) and then electrospun. With increasing DMF content, solution viscosity decreased continuously. Whereas, with increasing FeSO4·7H2O, it increased. Electrospun fiber mats with FeSO4·7H2O was calcined in the range of 600-1200℃.
