nanocomposite samples based on elastomer blends of butyl rubber (iir) and ethylene propylene diene monomer (epdm) were prepared using a laboratory scale two-roll mill in order to study the effect of cloisite 15a organoclay content (i.e., 1, 3, 5 and 7 wt%) on the mechanical and morphological properties  of  iir/epdm/cloisite  15a  nanocomposites  compared  to  the  unflled epdm/iir blends. rheo...

Significant effects of organoclay and poly(melamine-co-formaldehyde)-methylated (PMFM) impregnation on the mechanical, morphological, thermal characteristics raw pulai wood were investigated in this work. The material’s modulus elasticity (MOE) as well maximum compression force (MCF) impregnated organoclay/PMFM samples optimized using a designed experiment. MOE MCF models had R2 values 0.9228 0...

We have characterized a montmorillonite-based organoclay dispersed in three different nonaqueous solvents using a combination of x-ray scattering, small-angle neutron scattering (SANS), and ultrasmall angle neutron scattering (USANS), together with rheological measurements. Consistent with these measurements, we present a structural model for the incompletely dispersed clay as consisting of ran...

The microstructure, thermal stability, surface energy, and swelling characteristics of two kinds of commercial organoclays, before and after washing treatment with a mixture of H2O/ethanol, were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TG/DTG), wettability measurement, and swelling measurement. This study demonstrates that the external-surface physically adsorbed ...

A series of novel organoclays with antibacterial activity were synthesized using Ca-montmorillonite and Chlorhexidini Acetas (CA) by ion-exchange. The resultant organoclays were characterized using X-ray diffraction (XRD), high-resolution thermogravimetric analysis (HRTG) and Fourier transform infrared spectroscopy (FTIR). Their antibacterial activity was assayed by so-called halo method. In th...

good dispersion of nano-particles in polymer matrices is a crucial parameter in determining the final properties of polymer nanocomposites. in this work, the distributions of cloisite 30b, cloisite 10a and cloisite 93a in ptmeg, popular polyols in the polyurethane manufacturing, were investigated in the nano, micro and macro scales. this investigation was carried out using x-ray diffraction, rh...

Uptake and release capability of a new organoclay material were assessed with the final goal to evaluate its applicability in recovering REs from solutions. Capture have been tested towards La ions model solution, interaction mechanism reactions, active both capture processes, related nature operating process parameters. The studied system, polyamine-based organoclay, is able high efficiency. i...
