Ternary nanocomposites contain three components therefore, coimtless combinahons of materials and compositions are encountered in the literature and in practice. Polyolefins are almost always encoimtered as a component in nanocomposite blends, being the matrix, the dispersed phase, or both. Generally, semicrystalline thermoplastics such as polypropylene (PP) and polyethylene (PE) are very popular as the matrix component, while the dispersed phase consists of either another thermoplashc [15-17] or an elastomer [5,18-23]. Polyolefin-based thermoplashc elastomers, such as ethylene/propylene rubber, and other ethylene-based...

In this article, recent developments in the formation and properties of epoxy layered silicate nanocomposites are reviewed. The effect of processing conditions on cure chemistry and morphology is examined, and their relationship to a broad range of material properties elucidated. An understanding of the intercalation mechanism and subsequent influences on nanocomposite formation is emphasized. Recent work involving the structure and properties of ternary, thermosetting nanocomposite systems which incorporate resin, layered silicates and an additional phase (fibre, thermoplastic or rubber) are also discussed, and future research directions in this highly active area are canvassed. 

Ternary systems are becoming more widely reported with, in addition to epoxy and clay, other materials being present such as rubber, thermoplastic or fibres. Synergies need to be sought. likewise, the addition of additives such as flame retardants, either physically blended, or covalently-incorporated with the epoxy or amine need to be examined in nanocomposites, since this is one of the most important, ongoing requirements of transport industries such as aerospace.
