Rheology of Organoclay Nanocomposites:  Effects of Polymer Matrix/Organoclay Compatibility and the Gallery Distance of Organoclay

Macromolecules, 2003
The linear dynamic viscoelasticity, and transient and intermittent shear flows of organoclay nanocomposites, which were prepared with poly(ethylene-ran-vinyl acetate) (EVA), poly(ethylene-ran-vinyl alcohol) having 53 mol % vinyl alcohol (EVOH-53), or poly(ethylene-ran-vinyl acetate-ran-vinyl alcohol) having 5 mol % vinyl alcohol (EVAOH-5) were ...

Poly(Lactic Acid)/Organoclay Nanocomposites: Thermal, Rheological Properties and Foam Processing

Journal of Polymer Science, Part B: Polymer Physics, 2005
In this study, polymer nanocomposites based on poly(lactic acid) (PLA) and organically modified layered silicates (organoclay) were prepared by melt mixing in an internal mixer. The exfoliation of organoclay could be attributed to the interaction between

Structure and rheology of organoclay suspensions

Physical Review E, 2007
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.

Sorption of Isoxaflutole and DKN on Organoclays

Clays and Clay Minerals, 2004
AbstractSorption of the herbicide isoxaflutole and its main degradate, diketonitrile (DKN), to natural clays, SAz-1, SWy-2 and SHCa-1, and the organoclay derivatives (octadecylammonium (ODA) and hexadecyltrimethylammonium (HDTMA)) of these clays was investigated.

Influence of modifying organoclay on the properties of natural rubber/organoclay nanocomposites

Journal of Composite Materials, 2013
Montmorillonite 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, 2006
This 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 ...

Rheology of organoclay suspension

Colloid and Polymer Science, 2011
We 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.

Thermal characteristics of organoclay and their effects upon the formation of polypropylene/organoclay 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.

An infrared method to assess organoclay delamination and orientation in organoclay polymer nanocomposites

Polymer Engineering & Science, 2006
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.
