Summary: Development of 1-Dimensional Functional Ceramic Nanofibers by E-spinning
One-dimensional materials or structures are those exhibiting at least one dimension less
than 100 nm; average thickness of human hair is ~50,000 nm. There is a window to
develop nanoarchitectured ceramics for achieving benign tissue engineering,
photocatalysts, high performance gas sensors, photovoltaics and many other interesting
devices. Recently, bottom-up approaches have received increasing attention and
electrospinning is one of them. Electrospinning has been successfully used for making
polymer nanofibers for the past 70 years. It has seen its use in ceramics only for the past
3 years for the synthesis of 1-D nanofibers. Electrospinning uses electrical forces to
produce novel fibers of diameters in the range of 3 to 1000 nm, depending upon the
strength of the applied voltage between a drop of the precursor solution (or melt) and the
collecting surface.
We have employed electrospinning for fabricating a host of functional ceramics such as
stabilized zirconia (YSZ), doped ceria (GDC), strontium cerate (SrCeO3), titania (TiO2)
alumina (Al2O3) and lanthanum strontium manganite (LSM) as 1-dimensional nanofibers.
Various analytical techniques such as X-ray diffraction (XRD), Raman spectroscopy
(RS), thermogravimetry and differential scanning calorimetry (TG/DSC) and
transmission and scanning electron microscopy (TEM/SEM) together with the selected
area electron diffraction (SAED) and energy dispersive spectroscopy (EDS) were
employed for characterizing the processed fibers.
