Epoxy/MMT nanocomposites prepared by pressure induced flow processing
Melt intercalation of epoxy resins and montmorillonite (MMT) was carried out in order to improve toughness. Pressure induced flow (PIF) processing was introduced to further improve the mechanical properties. A series of testing methods such as X-ray diffraction (XRD), transmission electron microscopy (TEM), tensile and impact tests were used to study the characteristics and mechanical properties of nanocomposites. The results showed that the interlayer spacing of epoxy/MMT composites had increased, indicating that the molecular chain of epoxy would be intercalated in the layered silicate of MMT. Epoxy/MMT composites had better mechanical performance than those of pure epoxy resin and the properties significantly increased after PIF processing.
