Morphological Characterization of Brazilian Organ Clays Using AFM and SEM Studies
(2013-05)
A combination of SEM (Scanning Electron Microscopy) and AFM (Atomic Force Microscopy) techniques was used to characterise the morphology of Brazilian montmorillonites before and after intercalation of some organic compounds. ...
Thermal behaviour of intercalated 8-hydroxyquinoline (oxine) in montmorillonite clay
(Kluwer Academic Publ, 2004-01-01)
The composite montmorillonite-8-hydroxyquinoline (Swy-1-8-HQ) was prepared by two different processes and studied by using thermogravimetric analysis (TG/DTG and DSC), as well as helpful techniques as fluorescence in the ...
Preparation and characterization of light-cured methacrylate/montmorillonite nanocomposites
(John Wiley & Sons Ltd, 2010-10-14)
Polymer/clay nanocomposites were prepared from dimethacrylate monomers, commonly used in dental restorative resins, and an organically modified silicate (montmorillonite). The photopolymerization process was hardly affected ...
Uranium uptake by Montmorillonite-biomass complexes
(American Chemical Society, 2013-02)
Montmorillonite clays and biomass have noticeable metal sorption capacity. Clays or biomass are difficult to separate from the solution when used as sorbent materials. A methodology to retain biomass and improve separation ...
The Effect of Organophilic Montmorillonite on Compatibilization, Morphology and Mechanical and Thermal Properties of PA6/LDPE Blends
(Assoc Brasil PolimerosSao CarlosBrasil, 2013)
Synthesis and characterization of magnetic-montmorillonite and magnetic-organo-montmorillonite: Surface sites involved on cobalt sorption
(Elsevier Science, 2018-11)
Montmorillonite magnetic-clay nanoparticles (MtMag) and its exchanged product with hexadecyltrimethylammonium (O100MtMag) were synthetized by alkaline oxidation of ferrous sulfate, characterized by diverse techniques (XRD, ...
Montmorillonite-alginate beads: Natural mineral and biopolymers based sorbent of paraquat herbicides
(Elsevier Ltd, 2017-12)
Beads of alginate montmorillonite have been used for the first time as sorbent of the cationic pesticide paraquat (PQ). They are a green material because they are formed by a biopolymer and a clay mineral, and because they ...
Effect of sonication on the particle size of montmorillonite clays
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
This paper reports on the effect of sonication on SAz-1 and SWy-1 montmorillonite suspensions. Changes in the size of the particles of these materials and modifications of their properties have been investigated. The ...
Comparative Effect of Metallocene and Ziegler-Natta Polypropylene on the Exfoliation of Montmorillonite and Hectorite Clays to Obtain of Nanocomposites
(2007)
The present study was carried out on the effect of molecular weight and polydispersity of polypropylene (PP) obtained via Ziegler‐Natta or metallocene catalysis on the formation of nanocomposites with montmorillonite and ...
Biodegradable PLA/PBAT/Clay Nanocomposites: Morphological, Rheological and Thermomechanical Behavior
(Scrivener Publishing, 2016-05)
Poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT)-based nanocomposites were prepared by melt blending of PLA and PBAT with 5 wt% of unmodified (Cloisite Na) and modified (Cloisite 30B) montmorillonites. ...
