Abstract: Recent studies on inorganic/polymer nanocomposites
have shown enhancements in thermal, mechanical,
and chemical properties over the neat polymer without
compromising density, toughness, and processibility. When
nanoparticles are incorporated into the polymer matrix,
significant enhancements in thermal and mechanical properties
of the nanocomposite are observed. The present study
is focused on the preparation and characterization of nanosize
magnetite-reinforced PU composites, which induces
magnetic properties to a specific thermoplastic polyurethane
elastomer. The nanocomposites are prepared and the effects
of magnetite content on thermal, mechanical, and magnetic
properties of the nanocomposites are evaluated. Ultrasonication
was used to disperse the nanoparticles and break up
any large clumps and aggregates and followed by mechanical
mixing. The magnetic nanocomposites were characterized
by FT-IR spectroscopy, thermogravimetric analysis
(TGA), scanning electron microscopy (SEM), and vibrating
sample magnetometry (VSM). Characterization of the
magnetic nanocomposite by FT-IR showed a successful
incorporation of magnetite nanoparticles into the polymeric
matrix. TGA and magnetometry of the magnetic nanocomposites
revealed the amount of magnetite that was incorporated
into the polymeric phase. Finally, the corresponding
magnetization behavior of the nanocomposites was studied.
