Surfactant-supported organoclay for removal of anionic food dyes in batch and column modes: adsorption characteristics and mechanism study

Applied Water Science, 2023
This study aimed to create CTAB-modified bentonite organoclay (Bt@CTAB) by mixing the naturally occurring mineral bentonite (Bt) with the cationic surfactant cetyltrimethylammonium bromide (CTAB).

Effect of organoclay loading on the dielectric properties and charge dynamics of a PP-rubber nanocomposite

High Voltage, 2020
The addition of organoclay to a polypropylene-rubber (PP-rubber) blend, primarily introduced to compatibilise the immiscible polymer blend, invokes contrasting dielectric and charge dynamic behaviour depending on the filler loading level.

PP/organoclay nanocomposites for fused filament fabrication (FFF) 3D printing

eXPRESS Polymer Letters, 2019
3D printing has attracted a lot of attention over the past three decades. In particular the Fuse Filament Fabrication (FFF) technique, general materials require low shrinkage during cooling and viscous behavior during extrusion through a nozzle.

Mechanical, thermal and rheological characterization of polystyrene/organoclay nanocomposites containing aliphatic elastomer modifiers

Materials Research Express, 2020
In this study, organoclay containing polystyrene (PS) based nanocomposites were prepared by extrusion in the presence of aliphatic elastomer modifiers. Three different types of aliphatic elastomeric materials and three different types of organoclays were

Sub-surface mechanical properties and sub-surface creep behavior of wood-plastic composites reinforced by organoclay

Science and Engineering of Composite Materials, 2019
Wood-plastic composites (WPC) were manufactured from polypropylene, wood flour, maleic anhydride grafted polypropylene and organoclay. The sub-surface mechanical properties and the sub-surface creep behavior of the organoclay-based WPC were examined by ...

Synthesis and thermal properties of nanocomposites based on exfoliated organoclay polystyrene and poly(methylmethacrylate)

Nanocomposites, 2017
Exfoliated organoclay-polystyrene (OC-PS) and organoclay-poly(methyl methacrylate) (OC-PMMA) nanocomposites were prepared using novel modified/clay-polymer through both bulk polymerization and solution techniques.

Morphology and physico-mechanical properties of poly (methyl methacrylate)/polystyrene/polypropylene ternary polymer blend and its nanocomposites with organoclay: The effect of nature of organoclay and method of preparation

Polymers and Polymer Composites, 2022
This work presents the role of organoclay type (hydrophilic C30B vs hydrophobic C15A) and feeding mode (sequential vs. simultaneous) on a model ternary blend system poly (methyl methacrylate)/polystyrene/polypropylene (PMMA/PS/PP, 80/05/15).

Organoclay-polymer nanocomposites [PDF]

Zastita Materijala, 2014
The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved mechanical and thermal properties, as well as modified electrical properties and cost reduction.

In Situ Polymerization of Linseed Oil-Based Composite Film: Enhancement of Mechanical and Water Barrier Properties by the Incorporation of Cinnamaldehyde and Organoclay

Molecules, 2022
Linseed oil-based composite films were prepared with cinnamaldehyde (Cin) using a modified clay (organoclay) through in situ polymerization, which is the result of the interaction between Cin and organoclay.

Surface Structure of Organoclays [PDF]

Angewandte Chemie, 2004
The properties of organically modified clay minerals determine essentially the quality of polymer-clay nanocomposites. We investigate alkylammonium-micas with different alkyl chain length by molecular dynamics simulation as homogeneous mixtures and separated island structures on the mica surface (80 percent alkali exchange, 20 percent of the alkali ...
