  3. Abstract:
  4. The physical properties including glass transition temperature and permeability behavior of clay-filled epoxies are reviewed in this chapter. There is no consensus in the literature on how nanoclay affects the α-relaxation temperature in epoxy systems. This perhaps rises from the complexity of nanoclay morphology in polymeric resins and the interphase properties since morphology of nanoclay and interphase characteristics are two key parameters to control the glass transition process in epoxy nanocomposites. In addition, the possible existence of several α-transitions in montmorillonite-filled epoxies due to the existence of several relaxation domains may account for the controversial observations reported in the literature. Clearly, the permeability of nanoclay-filled epoxies is less than that of the neat polymers. Improvement of barrier properties in clay-filled nanocomposites depends on nanofiller content and its morphology. The chapter tries to give an updated view of the field to the reader, while it is intended to provide a firm background for future investigations. The chapter ends with a short glance at the applications of the nanoclay-filled epoxy composites to enlighten the industrial attractions of this family of nanocomposites
