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 ...

Cement substitution by organoclay – The role of organoclay type

Cement and Concrete Composites, 2015
Abstract In this paper three organically modified clays (OC) with different functional group of modifier and basal spacing ( d 001 ) but approximately the same alkyl chain length were considered in order to identify which parameter of OC is the most characteristic for the selection of appropriate OC for cement substitution.

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 ...

Optimizing organoclay stabilized Pickering emulsions

Journal of Colloid and Interface Science, 2011
Oil-in-water emulsions were prepared using montmorillonite clay platelets, pre-treated with quaternary amine surfactants. In previous work, cetyl trimethylammonium bromide (CTAB) has been used. In this study, two more hydrophilic quaternary amine surfactants, Berol R648 and Ethoquad C/12, were used and formed Pickering emulsions, which were more stable

Lamellar nanostructure in ‘Somasif’-based organoclays

Clays and Clay Minerals, 2007
AbstractThermally induced lamellar structure changes due to phase transition and degradation in organoclays based on a synthetic ‘Somasif’ mineral and two organic surfactants, di-methyl dihydro-ditallow ammonia chloride (DMDTA) and tri-butyl-hexadecyl phosphonium bromide (HTBP) were investigated by differential scanning calorimetry (DSC ...
