Fabrication and characterization of 1-D alumina (Al2O3) nanofibers in an electric field |

The technique of electrospinning was employed to fabricate uniform one-dimensional inorganic-organic composite
nanofibers at room temperature from a solution containing equal volumes of aluminum 2, 4-pentanedionate in acetone and
polyvinylpyrrolidone in ethanol. Upon firing and sintering under carefully pre-selected time-temperature profiles
(heating rate,
temperature and soak time), high-purity and crystalline alumina nanofibers retaining the original morphological features present
in the as-spun composite (cermer) fibers were obtained. Tools such as laser Raman
spectroscopy, scanning and transmission
electron microscopy together with energy dispersive spectroscopy and selected area electron diffraction were employed to follow the systematic evolution of the ceramic phase and its morphological features in the as-spun and the fired fibers. X-ray diffraction was used to identify the crystalline fate of the final product. |
