Preparation and Characterization of Unsaturated Polyester/Organic Montmorillonite Nanocomposites

Abstract:

This study uses in-situ polymerization method due to organic modified montmorillonite into unsaturated polyester to form a advanced montmorillonite / unsaturated polyester (MMT /UP) nanocomposites. Using of the blasting force generated in situ polymerization patterns show the formation of clay layers is exfoliation structure in polymer and improving of thermal properties, flame retardant properties, and mechanical properties.The d-spacing of organic modified clay could be determined whether the modifier was intercalated into the gallery of clay by applying the wide-angle X-ray diffraction (WXRD). The functional groups of modified clay were measured by Fourier infrared spectroscopy (FT-IR). The dispersion morphologies of MMT / UP nanocomposites were characterized by the wide-angle X-ray diffraction (WXRD) and transmission electron microscopy (TEM). The thermal properties and mechanical properties were investigated by thermal gravimetric analysis (TGA), limiting oxygen index meter (LOI), cone calorimeter (Heat Release Rate) and a dynamic mechanical analyzer (DMA).
