The Effect of Flower-Like Magnesium Hydroxide Nanostructure on the Thermal Stability of Cellulose Acetate and Acrylonitrile-Butadiene-Styrene

Flower-like magnesium hydroxide (Mg(OH)(2)) nanostructures were synthesized via a simple hydrothermal reaction at relatively low temperature. The Mg(OH)(2) nanostructures were then added to acrylonitrile-butadiene-styrene (ABS) and cellulose acetate (CA) polymers. The effect of Mg(OH)(2) nanostructures on the thermal stability of the polymeric matrixes has been investigated. The thermal decomposition of the nanocomposites shifts towards higher temperature in the presence of the Mg(OH)(2). The enhancement of thermal stability of nanocomposites is due to endothermically decomposition of magnesium hydroxide that releases of water and dilutes combustible gases. Nanostructures and nanocomposites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), differential thermal analysis (DTA), UL-94 test and limiting oxygen index (LOI) analysis.
