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 above
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 and polystyrene layered-silicate
nanocomposites using montmorillonite and
fluorohectorite.
