N2 - Layered double hydroxides (LDH) - poly(methyl methacrylate) (PMMA) intercalated-exfoliated nanocomposites were synthesized by solution polymerization of methyl methacrylate (MMA) in the presence of aminobenzoate organically-modified LDH. Preparations of 4-aminobenzoate organically modified LDHs were carried out by applying a chemical co-precipitation reaction. Structural and compositional details of LDH-AB were obtained with Fourier transformed infrared (FT-IR) spectroscopy, 27Al magic-angle spinning nuclear magnetic resonance (27Al MAS NMR), elemental analysis (EA), inductively coupled plasma (ICP) atomic absorption spectrometry and X-ray diffraction (XRD). The morphology of the LDH-AB in the PMMA matrix was identified by employing transmission electron microscopy (TEM), XRD, and UV/visible transmission spectroscopy. The thermal properties of the nanocomposites were enhanced and their Tg values as well as the decomposition temperatures shifted to a high temperature region as identified by the differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). For example, the Tg value and the decomposition temperature of the nanocomposites with 6.4% LDH-AB increased by 19 °C and 24 °C, respectively.
