| dc.description.abstract | Electrospun nanocomposite fibers were produced using polyvinylpyrrolidone (PVP),
polyacrylonitrile (PAN), multiwall carbon nanotubes (MWCNTs), and Ni0.6Zn0.4Fe2O4 (NiZn
ferrites) nanoparticles, and their physical properties, such as electrical, dielectrical, thermal,
acoustic, and magnetic were determined. In this dissertation, various system parameters (e.g.,
polymers, solvents, and viscosity) and process parameters (e.g., electrical potential, pump speed,
concentration, and distance) of the electrospinning process were studied in order to obtain the
optimum properties of the nanocomposite fibers. MWCNTs are conductors, and NiZn-ferrite
nanoparticles are semi-conductor materials; therefore, they alter the physical properties of
electrospun fibers in a different way. A comparison was made between MWCNT-based fibers
and NiZn ferrite-based fibers in terms of physical properties. As far as magnetic properties are
concerned, only NiZn ferrite-based fibers have been used because MWCNT-based fibers do not
exhibit magnetic properties. This dissertation determined to what extent the physical properties
change when nanoscale inclusions are encapsulated in nanocomposite fibers.
This study may open up new possibilities of using these products in various industrial
applications (e.g., filtration and separation, high frequency antennas, magnetic storage,
environmental sensors, biosensors, etc.) in the near future. | en_US |
