Characterization of Epoxy-Layered Silicates Filled with Fly Ash-Based Geopolymer

Abstract:

Several epoxy nanocomposites incorporating layered silicates and fly ash based geopolymer were analysed by utilising the wide angle X-Ray diffraction (XRD) to characterise the nanoscale dispersion of the layered silicates. The morphological study of the nanocomposites using X-ray diffraction was an operative method to identify exfoliated and intercalated structures in the nanocomposite. It was discovered that the exfoliated structure was observed in the nanocomposites filled with montmorillonite (MMT) and fly ash-based geopolymers; while the intercalated structure was found in the nanocomposites with 3wt% of MMT. The results suggest that that the addition of fly ash-based geopolymers into epoxy/MMT mixture may contribute to superior compressive properties, in comparison to those nanocomposites without geopolymer filler addition.
