Four cost effective organoclays were synthesized, characterized, and studied for the sorption of hydrophobic compounds (edible oil/grease and hydrocarbon oil) from aqueous solutions. Organoclays were prepared by cation exchange reaction of lattice ions (present onto the surface of laterite and bentonite clay minerals) with two surfactants, hexadecyl trimethyl ammonium chloride (HDTMA-Cl) and te...

This work aimed to compare the coating protection efficiency of C-steel using two kinds clay: a local Khulays clay (RCKh) from Saudi Arabia and commercial (CCIn) India. Clay-based polymer nanocomposites have unique layered structure, rich intercalation chemistry, availability at low cost. They are promising reinforcements for polymers. The raw both types was washed before being treated with NaC...

The micromechanical deformation mechanisms of a polylactic acid (PLA)/natural rubber (NR) blend (PLA/NR 90/10 wt%) and its organoclay filled bionanocomposites have been investigated by small and wide angle X-ray scattering (SAXS–WAXS) under tensile conditions. The addition of NR to a PLA matrix changed the brittle fracture of PLA to a ductile deformation through the debonding of the rubber drop...

In this work, nanocomposites were developed and evaluated using high-density bio polyethylene (BPEAD)/Cloisite 20A (3 6%)/commercial antimicrobial additive (0,5 1%) containing 1% of zinc pyrithione dispersed in vinyl acetate (EVA). The samples prepared a single screw extruder the melt intercalation technique then by flat extrusion to obtain films. X-ray diffraction (XRD) showed an increase basa...

This study investigated the effect of Cloisite15A (C15A) organoclay in the substrate layer on the performance of reverse osmosis (RO) membranes. The substrate of the RO membranes was modified using different loading of C15A (ranging from 0.3 - 0.7 wt%) within polysulfone (PSf) substrate and the polyamide (PA) selective layer was formed on the top. Effect of the modified substrate layer on the w...
