Octadecylamine modified montomorillonite/poly(styrene-co-acrylamide) (Oct-MMT/PSTAM) nanogels with unique morphologies of core/shell and core/shell/shell structures were fabricated. The transmission electron microscopy (TEM) images of The as-prepared composites revealed the formation of double and triple coated structures with average size of 152 nm and 52 nm, respectively. New nanocomposites (MHs(1-3)) were fabricated by impregnating Oct-MMT/PSTAM latex with core/shell/shell structure onto crosslinked poly(sodium acrylate-co-acrylamide) (PSAAM) of various molar ratio. PSAAM was selected as a support material because it has a higher swelling ratio and will achieve an expected compatibility with MMT/PSTAM nanogel. These MHs nanocomposites were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray fluorescence (XRF) and differential scanning calorimetry (DSC).
