AbstractWe prepared polypropylene nanocomposites based on a modified organoclay with isobutyl trimethoxysilane to investigate the effects of such modifications of organoclay on the microstructure and properties of the nanocomposite. The organoclay was preliminarily intercalated with distearyldimethylammonium bromide via an ion exchange before being ...

Structure and rheology of organoclay suspensions
Physical Review E, 2007We 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.

Influence of modifying organoclay on the properties of natural rubber/organoclay nanocomposites
Journal of Composite Materials, 2013Montmorillonite nanoclay was modified with octadecylamine and compounded with natural rubber by the melt mixing method. Influence of the modification on the properties of natural rubber/organoclay nanocomposites was investigated. Furthermore, structures of the natural rubber/clay nanocomposites were characterized by X-ray diffraction and scanning ...

Organoclay-enzyme film electrodes
Analytica Chimica Acta, 2006This paper aims at showing the interest of organoclays (clay minerals containing organic groups covalently attached to the inorganic particles) as suitable host matrices likely to immobilize enzymes onto electrode surfaces for biosensing applications. The organoclays used in this work were natural Cameroonian smectites grafted with either aminopropyl ...

Journal of Thermoplastic Composite Materials, 2019
Nanocomposites composed of polypropylene (PP), organoclay, ethylene acrylic acid (EAA), and maleic anhydride-grafted polypropylene (PP- g-MA) were prepared using the melt mixing technique, and their thermal stability properties were investigated. PP- g-MA and EAA were used as compatibilizers in the nanocomposites.

Polymer Bulletin, 2000
We have examined thermal characteristics of two types of organically modified montmorillonite (OMMT) with different alkylammonium cations and their effects upon the formation of PP nanocomposite, when using a maleic anhydride grafted polypropylene oligomer (maPP) as a compatibilizer.

Abstract Assessing the degree of organoclay delamination and layer alignment is crucial to deliver consistent properties of nanocomposite materials. A simple infrared technique is discussed that permits quantitative determination of these organoclay dispersion parameters in a nanocomposite.

Rheology of organoclay suspension
Colloid and Polymer Science, 2011We have studied the rheological properties of clay suspensions in silicone oil, where clay surfaces were modified with three different types of surfactants. Dynamic oscillation measurements showed a plateau-like behavior for all the organoclay suspensions studied, which indicated more solid-like characteristics.

Adsorption of Xylene by Organoclays
Clays and Clay Minerals, 1975AbstractBased on X-ray powder diffraction measurements of swelling, thermodynamic analysis of adsorption and kinetics, a mechanism of interaction between xylene isomers and two organoclay complexes was derived. The work is intended to resolve the factors which make possible the chromatographic separation of the xylene isomers with organoclays ...
