Epoxy nanocomposites based on layered silicates and other nanostructured fillers

1 The three possible main reactions during cure of an epoxy resin with an amine - (/) primary amine-epoxy addition, (//) secondary amine-epoxy addition, (///) etherification (from Chiao, L., (1990) Macromolecules 23 1286). [Pg.30]

2 Rheology of epoxy layered silicate network precursors [Pg.32]

The rheological behaviour of organoclay-filled epoxy resins prior to cure can significantly influence the processing of the nanocomposite and therefore the properties of the final material. Becker et investigated the effect of an [Pg.32]

The synthesis of polymer nanocomposites can be divided into three main classes, i.e. melt intercalation, intercalation of the polymer from solution and in-situ polymerization. Whilst synthesis via melt intercalation is not applicable to thermosetting systems, a few reports were made on the epoxy nanocomposites formation from solution, mainly as a way to get intimate mixing or to [Pg.34]
