Abstract:
In many of the cases studied, polymer-clay
nanocomposites are materials that have improved thermal
properties. Furthermore, most of the nanocomposite
systems reported so far show reduced flammability. The
delaminated versions of nanocomposites also offer
measurable improvements in a variety of physical
properties. The intercalated versions offer the reduced
flammability benefits, but with less improvement in
physical properties. Many issues are unresolved as to
the mechanism of these property enhancements. We report
here on our continuing study of the mechanism of
flammability reduction with recent results for
polypropylene-graft-maleic anhydride and polystyrene
layered-silicate nanocomposites using montmorillonite
and fluorohectorite.
