Nanocomposites result from the combination of materials
with different properties at the nanometer scale. Some
examples of these include: polymers combined with
layered-silicate, polymers combined with nano-silica,
hybrid materials prepared by sol-gel methods and POSS
nanocomposites. All these materials exhibit many such as
improved thermal stability, reduced improved mechanical
properties; etc. However, for successful preparation of
nanocomposites, and for their subsequent incorporation
into end-products, nanocomposites must maintain their
unique chemical and physical properties during
processing. We report here our recent results, which
show improved thermal stability (140 deg C higher) for
new organic cationic treatments used to compatibilize
layeered silicates with polymers and monomers. This work
was motivated by concern about processing degradation,
which we observed in polymer/montmorillonite (MMT)
