Resumen:
Epoxy-based thermosetting polymer resins are widely used in several industrial applications because of their outstanding characteristics such as light weight, good chemical resistance and improved thermal and mechanical properties. However, epoxies are brittle and they show a natural tendency to absorb significant amounts of moisture when exposed to humid conditions. These factors have detrimental effects on the physical properties of epoxies and can therefore greatly compromise the materials performance. A novel alternative to overcome these problems is the reinforcement with fillers. Clays can effectively enhance thermal, mechanical and barrier properties of epoxy resins even at low loadings. It is well known that the enhancement in the nanocomposite properties strongly depends on the level of clay dispersion in the polymer matrix. Two different morphological structures are mainly achievable: nanocomposites with either intercalated or exfoliated clay mineral. Clays can be organically modified through ion exchange reactions to facilitate the intercalation of polymers into the interlayer galleries and therefore facilitate the formation of an exfoliated structure.
