Herein, we report on the synthesis of carbon nanocomposite fibers reinforced with iron oxide and various amount of silica through electrospinning method. Polyacrylonitrile (PAN) is selected as the carbon source. Iron nitrate (Fe(NO3)3) and tetraethyl orthosilicate (TEOS) are used as the precursors of iron oxide and silica, respectively. PAN is dissolved into Dimethylformamide (DMF) to serve as the matrix. And fibers are fabricated through electrospinning the mixture of matrix solution and precursors. Finally, the desired composites are obtained after an additional thermal treatment. The operation parameters are tuned to achieve uniform and bead-free morphology for different samples combining their rheology properties. Scanning electron microscope (SEM) is used to characterize the micro morphology. Fourier transform infrared spectroscopy (FT-IR), Mossbauer spectra and thermogravimetric analysis (TGA) are applied to determine the composition and thermal stability of the carbon nanocomposite fibers. The magnetism, conductivity and fluorescent properties of the products will also be studied.
