Synthesis, characterisation and application of organoclays [PDF]

, 2006
This thesis focuses on the synthesis and characterisation of organoclays. X-ray diffraction has been used to study the changes in the basal spacings of montmorillonite clay and surfactant-intercalated organoclays.

Reactive Red 195‐loaded halloysite for cotton dyeing and printing: Adsorption, characterisation and comparison with conventional exhaustion dyeing

Coloration Technology, EarlyView.
Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

The Filler Network Index: A Viscosity‐Independent Rheological Criterion for Quantifying Silica Architecture in Unvulcanized Rubber Compounds

SPE Polymers, Volume 7, Issue 4, October 2026.
SEM images of unmodified (U30) and TESPT‐grafted (U30‐SCA) silica compounds show that pre‐grafting eliminates agglomerates. Stress relaxation data fitted with a constrained five‐element Weichert model give discrete relaxation times (τ1$$ {\tau}_1 $$‐τ5$$ {\tau}_5 $$), both reduced by grafting. Their ratio, the Filler Network Index (FNI = τ1$$ {\tau}_1 $

β‐Cyclodextrin Immobilized in Geophagic Clay Sheets for the Absorption of Dyes From Wastewater Using a Fixed‐Bed Method

Water Environment Research, Volume 98, Issue 10, October 2026.
β‐Cyclodextrin‐functionalized geophagic clay was applied in a fixed‐bed column for the removal of rhodamine B (RhB) and methyl orange (MO). RhB interacts via electrostatic attraction and hydrogen bonding, while MO undergoes cavity inclusion complexation and hydrogen bonding within the βCD structure.

Development of Organoclay as an Artificial Micro Substrate for Chemoautotrophic Biofloc Aquaculture Systems (BFT)

Fishes
This study investigated the characterization and application of organoclay formulations in a chemoautotrophic biofloc system. Organoclays were produced using the calcination method and bentonite, chitosan, corn, and tapioca starches as ingredients ...

A thermoanalytical assessment of an organoclay [PDF]

Journal of Thermal Analysis and Calorimetry, 2011
High resolution thermogravimetric analysis (TG) has attracted much attention in the synthesis of organoclays and its applications. In this study, organoclays were synthesised through ion exchange of a single cationic surfactant for sodium ions, and characterised by methods including X-ray diffraction (XRD) and TG.

Impact of Chitosan Incorporation on PBAT Composite: Thermal, Viscoelastic, Mechanical, and Morphological Properties

Journal of Applied Polymer Science, Volume 143, Issue 36, September 20, 2026.
The abstract explains the impact of various concentrations of chitosan on PBAT composite. Indeed, the composite is produced at increasing concentrations of chitosan (10%, 20%, and 30%). The decrease in the tensile strength with increased conc. of chitosan was recorded. Furthermore, the same impact was recorded for TGA analysis.
