Abstract
Herein, different morphologies of α-Fe2O3 nanostructures were successfully prepared via hydrothermal route using K3[Fe(CN)6] as starting reagent. The morphology, crystalline structure, composition and magnetic properties of as-obtained α-Fe2O3 nanostructures were extensively characterized by X-ray diffraction patterns, field emission scanning electron microscopy, Fourier transform infrared spectroscopy and vibrating sample magnetometer. Moreover, composite films of α-Fe2O3 and epoxy resin were prepared by molding of α-Fe2O3 and epoxy resin at various mass rations and thickness. The obtained composite films were utilized as electromagnetic waves absorber and our results showed that due to excellent electromagnetic waves absorption ability, these composite films can be a promising candidate to use as electromagnetic absorber. Moreover, effect of reaction time and temperature, pH, Fe source and etc. on morphology of products and consequently on electromagnetic absorption property were well studied.
