“…It shows the basal spacing for the DS-LDH is 2.56 nm from the diffraction peak at 2h = 3.45°. The individual dodecyl sulphate chain length and LDH sheet thickness are 2.07 and 0.48 nm, respectively [15,16]. As a result, the increase in basal spacing is due to the intercalation of mono-layer dodecyl sulphate molecules between the hydrotalcite sheets.…”

Ethylene propylene diene terpolymer (EPDM)/MgAl layered double hydroxide (LDH) nanocomposites have been synthesized by solution intercalation using organically modified LDH (DS-LDH). The molecular level dispersion of LDH nanolayers has been verified by the disappearance of basal XRD peak of DS-LDH in the composites. The internal structures, of the nanocomposite with the dispersion nature of LDH particles in EPDM matrix have been studied by TEM and AFM. Thermogravimetric analysis (TGA) shows thermal stability of nanocomposites improved by %40°C when 10% weight loss was selected as point of comparison. The degradation for pure EPDM is faster above 380°C while in case of its nanocomposites, it is much slower.

Several types of synthetic or semi-synthetic layered materials are considered, namely the phyllosilicates (clays), silicic acid (magadiite), layered double hydroxides (LDHs), zirconium phosphates (ZrPs), and di-chalcogenides. The main advantage of synthetic clays is their chemical purity (e.g. absence of amorphous and gritty contaminants, as well as arsenic, iron, and other heavy metals), white to transparent color that assures reproducibly of brightly colored products, as well as a wide range of aspect ratios, p ¼ 20 to £6000. Several large scale production facilities have been established. The synthetic clay and LDH industries are oriented toward big volume markets: catalysis, foodstuff, cosmetics, pharmaceuticals, toiletry, etc. The use of these materials in PNCs is limited to synthetic clays and LDHs, mainly for reinforcement, permeability control, reduction of flammability, and stabilization, e.g. during dehydrohalogenation of chlorinated macromolecules. The use of lamellar ZrPs and di-chalcogenides is at the laboratory stage of functional polymeric systems development, e.g. for electrically conductive materials, catalysts or support for catalysts, in photochemistry, molecular and chiral recognition, or in fuel cell technologies, etc. Copyright # 2007 John Wiley & Sons, Ltd.KEYWORDS: polymeric nanocomposites; nanoparticles; clay; layered double hydroxides; matrix POLYMERS FOR ADVANCED TECHNOLOGIES Polym.

“…50 Fulvic, humic and acrylic acids, however, seem to have been successfully intercalated into Montmorillonite at low pH (lower than 4). Ramos-Tejeda and coworkers 52 studied the effect of humic acid (HA) in flow properties of Mt dispersions, finding a significantly high adsorption of HA onto the platelets, as previously verified by Tombácz et al 53 . The authors concluded that adsorption is not only explained by electrostatic attraction on the edges (which is the main phenomenon), but also by repulsive interactions between faces and HA molecules.…”

“…These issues were later attributed to the partitioning of the RAFT agent, that cannot be properly transported between aqueous phase, monomer droplets and the polymerizing particles and to the superswelling effect of the polymer particles. [48][49][50][51][52][53][54] In 2002, 55 a new method has been described for the effective ab initio RAFT emulsion polymerization. In this novel strategy, hydrophilic RAFT agents that contain short stabilizing segments of hydrophilic monomers were used in the emulsion polymerization of hydrophobic monomers to form amphipathic species that self-assemble to form micelles.…”

“…In the template synthesis (sol-gel technology) technique, the clay minerals are synthesized in the presence of an aqueous solution of the polymer matrix. This method is widely used for the synthesis of nanocomposites based on layered double hydroxides [50][51][52] however, some disadvantages of the technique must be considered for layered silicates. The high temperature required to synthesize most clay minerals may cause the decomposition of the polymer matrix.…”
