Sulfonated styrene-(ethylene-butylene)-styrene triblock copolymer (SSEBS) was synthesized by reaction of acetyl sulfate with SEBS. SSESB-clay nanocomposites were then prepared from hydrophilic Na-montmorillonite (MT) and organically (quaternary amine) modified hydrophobic nanoclay (OMT) at very low loading. SEBS did not show improvement in properties with MT-based nanocomposites. On sulfonation...

this article presents the method of extraction-preconcentration of lead, cadmium, and nickel ions from food samples using the ghezeljeh montmorillonite nanoclay (geleh-sar-shoor) as a new native adsorbent in batch single component systems. the extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (spe) method followed by atomic absorption spectrosco...

this paper describes the effects of reinforcement by randomly distributed nylon fibers and addition of nanoclay on some engineering properties of a typical asphalt concrete. the properties of asphalt concrete reinforced by different percentages of 25 mm nylon fibers have been compared with those of the mixtures containing different percentages of nanoclay and those in which both the fibers and ...

Engineered nanoparticle–support interaction is an effective strategy for tuning the structures and performance of engineered nanoparticles. Here, we show that dehydroxylation kaolinite nanoclay as support could induce zinc oxide–kaolinite interactions. We used free energy theory, electron microscopy, X-ray photoemission spectroscopy to identify strengths between metal oxides underlying induced ...

The increasing environmental pollution with petroleum-based plastics has advanced research on biodegradable polymers. Thermoplastic starch (TPS) is one promising candidate due to wide availability from various renewable sources, low cost and biodegradability. However, TPS significant shortcomings, as high water sensitivity mechanical properties. An approach overcome these drawbacks adding nanof...

This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...

<p>Among the various kinds of reinforcing element, Multi Wall Carbon Nano-tubes (MWCNT) and Nanoclay have found much more attention as a filler element to upgrade mechanical properties polymer composite material. In this paper, production hybrid nanocomposites effect MWCNT nanoclay on been evaluated. nanocomposites, are embedded in epoxy resin. The processing nanocomposite is always diffi...

ABSTRACT Background: In timber structures, connections are the most important and critical section which supply strength of each structural element. The aim this study was evaluation behavior epoxy resin reinforced by nanoclay (at three levels) on pull-out glued-in GFRP rods in glulam. For purpose, two with lengths (50, 150 250 mm) diameters (6.4, 12.7 19.1 were inserted at opposite sides glula...

Glass ionomer cement (GIC) represents a major transformation in restorative dentistry. Wear of dental restoratives is a common phenomenon and the determination of the wear resistance of direct-restorative materials is a challenging task. The aim of this paper was to evaluate the wear resistance of novel glass ionomer cement by two wear-test methods and to compare the two wear methods.The wear r...
