Organic Modification Of Montmorillonite With Low Molecular Weight Polyethylene Glycols And İts Use İn Polyurethane Nanocomposite Foams
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2010-10-20)
This paper deals with the preparation of organoclays by intercalating poly(ethylene glycol) molecules (PEG) between Na montmorillonite (Na-MMT) layers in a clay-water suspension system. X-ray diffraction (XRD) results of ...
The Modification Of Na-Montmorillonite By Salts Of Fatty Acids: An Easy İntercalation Process
(Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2010-11-20)
The organic modification of Na-montmorillonite (Na-MMT) clay by a reaction with the sodium salts of octadecanoic acid (SOD) and dodecanoic acid (SDD) was studied for the production of effectively intercalated and organophilic ...
Effectiveness of Amino Alcohol-Based Surface-Applied Corrosion İnhibitors in Chloride-Contaminated Concrete
(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2007-06)
In the present study, the effectiveness of two generations of amino alcohol (AMA) based surface-applied corrosion inhibitors (SACI) is investigated. The inhibitors were applied on the surface of the hardened concrete. The ...
The mechanism of β- Carotene adsorption on activated montmorillonite
The variations in the structure of mineral during adsorption have been examined comparing the results of X-ray diffraction (XRD), differential thermal analysis (DTA), thermogravimetry (TG) and infrared (IR) spectroscopy ...
β-Carotene adsorption on acid-activated montmorillonite
The adsorption of β-carotene from solution in benzene on acid-activated Canakkale montmorillonite of Turkey has been investigated. The adsorption isotherm had two steps. The first step was of the Langmuir type, and the ...
Kinetics of the thermal dehydration of acid-activated montmorillonite by the rising temperature technique
The activation energies of dehydration and combustion of organic materials in a clay sample, and of dehydration of natural and acid-activated montmorillonite have been determined using a rising temperature programme ...
Thermal investigation of acid-activated clay minerals
Samples of the clay mineral from the Çanakkale reserve in Turkey were activated with sulphuric acid under three different sets of conditions. DTA and TG curves of both natural and activated samples were then obtained and ...
The Mechanism of Acid Activation of Montmorillonite

Surface Modification of Nanoclays with Styrene-Maleic Anhydride Copolymers
(Scientific Research, 2017)
This study presents the modification of surfaces of nanoclays, halloysite nanotubes (HNT) and sepiolite (SEP), with styrene-maleic anhydride copolymers (SMA) via esterification reaction between hydroxyl groups of the ...
