Abstract
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) nanocomposites.
