Desorption of organic from clay by washing up to ten times with water showed that not all organic was removed since the d-spacing of organic/clay did not collapsed to that of clay alone.In the competitive adsorption studies, both plasticizers (PEG600 or M600 Enhancing the Barrier Properties of Biopolymers using Clays the competitive adsorption of a polymer and a plasticizer onto one of the more successful clays. In order to enhance the chances of a successful outcome PVOH was selected as the polymer for study. Earlier work at Sheffield [3] and the work of Strawhecker and

Preferential Intercalation in Polymer-Clay Nanocomposites

When polymer-clay nanocomposites are prepared from a polymer of broad molecular mass distribution, the question arises whether the clay scavenges the low molecular mass fractions or prefers to receive the larger molecules which might provide bridges between nanoparticles. This is the first report of competitive sorption experiments for molecular mass in polymer-clay nanocomposites and shows Ionic conductivity enhancement of the plasticized PMMA/LiClO 1/9/2002 · Intercalating polymer in the layered clay host can produce polymer nanocomposite electrolyte with huge interfacial area. From our prior studies [19] , [20] , a higher interfacial area not only sustains the mechanical properties of PMMA-based gel polymer electrolyte but also increases the dissolubility of the lithium salts due to its higher dielectric property.

1/9/2011 · Nanofiller incorporation into the matrix can be carried out using three main techniques:4 (1) the solvent intercalation route, which consists of swelling the layered silicates in a polymer solvent to promote macromolecule diffusion in the clay interlayer spacing; (2) the in situ intercalation method, for which the layered silicates swell in the monomer or monomer solution before polymerization Characterization of Extruded Thermoplastic Starch Reinforced by Montmorillonite Nanoclay 14/2/2013 · The purpose of this study was to understand how the montmorillonite (MMT) nanoclay influences physical and mechanical properties of thermoplastic starch (TPS), which was produced by a conventional extrusion procedure. MMT nanoclay was added at 0, 4, and 8 % (w/w) concentrations. Transmission electron microscopy (TEM) showed most MMT platelets existed in tactoid structure in the starch matrix

This study explicates the optimum condition for effective and efficient uptake of cationic dye onto raw and modified (acid activated and calcined) Ekowe clay. The clay modification spanned 750 o C calcination of RS to produced RCS and 0.5MH 2 SO 4 Poly(methyl methacrylate) and Polystyrene/Clay Nanocomposite 3/5/2001 · Poly(methyl methacrylate) (PMMA) and polystyrene (PS)/clay nanocomposites were prepared via in-situ bulk polymerization. The compatibility of the initiator and monomer with the clay surface was found to profoundly affect the clay dispersion. By using a surfactant containing a polymerizable group to modify the clay surface, exfoliated PMMA and PS/clay nanocomposites were synthesized. The clay
