Characterization of hexadecyltrimethylammonium-organoclay and its individual components by thermal techniques
The properties of the materials determine their potential applications. The aim of this article is to study the properties of the organoclays using simple and rapid technologies. Organoclays with different surfactant ...
Ablative Properties of Polyurethanes Reinforced with Organoclay
(John Wiley & Sons Inc., 2020-01)
Ablation resistance and mechanical properties of polyurethanebased composites containing different amounts (up to 5 wt%) of organoclay were correlated with the morphological characterization. The crosslinking density of ...
Morphological Characterization of Brazilian Organ Clays Using AFM and SEM Studies
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. ...
Barrier properties and structural study of nanocomposite of HDPE/montmorillonite modified with polyvinylalcohol
(Hindawi Publishing Corporation, 2013-01)
In this work was studied the permeation of COin films of high-density polyethylene (HDPE) and organoclay modified with polyvinylalcohol (MMTHDTMA/PVA) obtained from melt blending. Permeation study showed that the incorporation ...
Synthesis and characterization of HDTMA-organoclays: Insights into their structural properties
(Sociedade Brasileira de Química, 2015-02)
This study aims to synthesize and characterize organoclays developed from an Argentinian montmorillonite (Bent) using hexadecyltrimethylammonium bromide (HDTMA-Br) as the intercalation agent. Subsequently, an adsorption ...

Non-isothermal crystallization of PCL/CLAY nanocomposites
(VBRI Press, 2018-06-14)
In this work, Differential Scanning Calorimetry (DSC) was used to study the crystallization behavior of nanocomposites based on polycaprolactone (PCL) reinforced with organo-montmorillonite (C20A) and organo-bentonite ...
Linear viscoelasticity, extensional viscosity, and oxygen permeability of nanocomposites based on propylene copolymer and organoclay
(John Wiley & Sons Inc, 2018-02-13)
Random propylene-terpolymer (PEBC)/organophilic montmorillonite nanocomposites were prepared by melt mixing, using PEBC modified with maleic anhydride (PEBCg) as compatibilizer. Clay concentrations up to 8 wt %, ...
Polycaprolactone/organoclay biodegradable nanocomposites: Dissimilar tendencies of different clay modifiers
(VBRI Press, 2018-11)
In this work, biodegradable nanocomposites based on polycaprolactone (PCL) reinforced with 2.5, 5.0 and 7.5 wt.% of two different clays, a commercial organo-clay (Cloisite 20A, C20A) and a laboratory modified bentonite ...
