Abstract
The development of polymer layered silicate (PLS) nanocomposites goes back over 20 years now, and yet they still have not achieved their full potential. A principal reason for this is the difficulty of obtaining a truly exfoliated nanostructure. The fabrication procedure for such PLS nanocomposites based upon epoxy resin includes several stages, including dispersion of the clay in the resin, intercalation of the resin into the clay galleries, and finally curing of the nanocomposite system. Many attempts have been made to improve the degree of exfoliation in the final nanostructure by modifying the procedures involved in these fabrication stages, and the usual approach is to examine the nanostructure, by techniques such as small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM), as a function of the fabrication procedure. We show here, however, that thermal analytical techniques, and in particular differential scanning calorimetry, can complement the techniques of SAXS and TEM in the search for ways in which to achieve improved degrees of exfoliation in PLS nanocomposites based upon epoxy resin.
