The present investigation is targeted to prepare nanocomposites based on binary blends of
polyetherimide (PEI)-silicone rubber incorporated with varied loadings of nanotitanium dioxide
particles. Nanocomposites have been prepared by melt blending process using twin screw
extruder. Thermal properties of the developed nanocomposites have been investigated with
the help of thermogravimetric analyzer (TGA) and dynamic mechanical analyzer (DMA).
Scanning electron microscopy (SEM) is used to analyze the morphological properties of the
nanocomposites. Mechanical properties (tensile strength, tensile modulus, elongation at break,
impact strength) of the nanocomposites have been evaluated by universal testing machine
(UTM). Mechanical testing results reveal that there is 35% increase in tensile strength, 3%
increase in tensile modulus and 41% increase in impact strength at 1 phr loading of nanotitanium
into blend polymer matrix. The nanocomposite having 1 phr nano-titanium has got the highest
thermal stability than the others. DMA results indicate that at 50°C nanocomposites having
1 phr nano-titanium reveals 69% increase in storage modulus as compared to pure blend
system. SEM micrographs clearly indicate that the nanocomposite with 1 phr loading of nano
titanium has the smallest domain size as compared to other nanocomposites .This may be
due to uniform and homogeneous dispersion of 1 phr nanotitanium in polymer matrix followed
by fairly good polymer filler interaction.
