Abstract
|
Nanocomposites of polystyrene (PS) was prepared with new styrenic ionic
liquid, N-(4-vinyl benzyl)-(N,N-dimethylamino) pyridinium chloride[VBMAP], surfactants
used as organic modifications for the clays. Sodium montmorillonite (Na-MMT) was
successfully modified by [VBMAP] to become OMMT through cation exchange technique
which is shown by the increase of basalspacing of clay by XRD. The composite material
based on polystyrene and organo-modified montmorillonite (OMMT) was prepared by
insitu polymerization and characterized. The morphology of the polymer/clay hybrids was
evaluated by X-ray diffraction (XRD) ,transmission electron microscopy (TEM) and
scanning electron microscopy (SEM), showing good overall dispersion of the clay. The
thermal stability of the polymer/clay nanocomposites were enhanced, as evaluated by
thermogravimetric analysis.
