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.

Modified resol type phenolic resin nanocomposites as surface metal coatings

SPE Polymers, 2021
Nanocomposites based on resol resin as a matrix and prepared organoclay, from Egyptian bentonite clay, as reinforcement material were synthesized. The effect of organoclay content (i.e., 0.5, 1.0, 1.5, 2.0, and 2.5 phr) on the properties of the prepared ...

Fabrication of hemp fiber-reinforced green composites with organoclay-filled poly(butylene succinate) matrix by pultrusion process

Science and Engineering of Composite Materials, 2014
Hemp fiber-reinforced green composites with organoclay-filled poly(butylene succinate) (PBS) matrix were fabricated by pultrusion process. Morphological studies revealed that the clay particles were intercalated/partially exfoliated when the clay content

Sorption of Isoxaflutole and DKN on Organoclays

Clays and Clay Minerals, 2004
AbstractSorption of the herbicide isoxaflutole and its main degradate, diketonitrile (DKN), to natural clays, SAz-1, SWy-2 and SHCa-1, and the organoclay derivatives (octadecylammonium (ODA) and hexadecyltrimethylammonium (HDTMA)) of these clays was investigated.
