Abstract: Exfoliated polystyrene (PS)/ZnAl layered double hydroxide (LDH) narlocomposites have been synthesized via emulsion polymerization ill the presence of N-lauroyl-glutarnate surfactants and long-chain n-hexadecane. The samples were characterized using elemental analysis, Fourier transform infrared (FTIR) spectrum, X-ray diffraction (XRD), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). The XRD and TEM results demonstrate that the exfoliated ZnAl-LDH layers of 50-70 nm width and about 1 nm thickness were well dispersed at molecular level in the PS matrix. And the completely exfoliated PS/LDH nanocomposites can be obtained even at the 10 wt% LDH loading. When the 50% weight loss was selected as a comparison point, the decomposition temperature of exfoliated PS/LDH sample with 5 wt% LDH was ca. 28 degrees C higher than that of pure PS.
