| Abstract: | Polystyrene/nano-SiO2
composites with different silica contents have been prepared by using nano-silica
particles of
10 nm and polystyrene obtained in batch
jacketed reactor with self-tuning PID (STPID) temperature control. The
relationship between final properties of nanocomposite material and
polymer matrix properties with control has been studied and the composites thus
prepared are characterized by means of differential
scanning calorimetry (DSC),
thermal gravimetric analysis (TGA),
scanning electron microscope (SEM)
and hardness tests. It is observed that higher mechanical and thermal properties
of nanocomposites could be obtained using polystyrene produced with STPID
temperature control under optimal conditions which are precalculated for
average number of molecular weight of 52000 and monomer conversion of 50%. It is also found that
hardness and thermal stability of nanocomposite materials increase with
increasing nano-silica contents,
as expected. The same thermal stability increase is observed in DSC
thermograms. |
