Abstract

ABSTRACTHerein we investigated new type of poly(methyl methacrylate) (PMMA) nanocomposites by solution polymerization of methyl methacrylate (MMA) in the presence of multimodified Layer double hydroxide (LDHs). Two different anionic exchange capacities LiAl and MgAl types of LDHs were used and modified with cocoamphodipropionate (K2) and sodium dodecyl sulfate by the anionic ion exchange method. The modified and pure LDHs have been characterized by X‐ray diffraction (XRD), and Fourier transform infrared spectroscopy. Solution‐polymerized PMMA nanocomposite LDH dispersion morphology was investigated by transmission electron microscopy and XRD. Thermo‐mechanical, gas barrier, and optical clarity properties of nanocomposite systems are greatly improved relative to the virgin PMMA.
