Morphology-controlled synthesis of Al/Fe_2O_3 nano-composites via electrospinning

摘要

In this article, nano-scale Al/Fe_2O_3 composites with different morphologies were successfully obtained by a simple electrospinning technique, which is based on a surfactant(polyvinyl pyridine, PVP) in a mixture of N,N-dimethylformamide(DMF) and 2-propanol. The electrospun Al/Fe_2O_3 composites exhibited a crystal structure and phase composition by X-ray diffraction analysis. The different morphologies of the Al/Fe_2O_3 composites were also observed through scanning electron microscopy and transmission electron microscopy. It was found that the rather simple electrospinning method used to prepare the morphology-controlled Al/Fe_2O_3 composites may have the potential for preparation of propellants, explosives, and pyrotechnics in the future.
