Abstract:A vermiculite (VMT) dispersion in water was blended with aqueous poly(vinyl alcohol) (PVA). The properties of the PVA–VMT nanocomposites greatly depended on the preparation procedure because of the chemical reactions and physical interactions involved. The samples were prepared in two steps to investigate the properties of the PVA–VMT nanocomposites. The VMT was first pretreated and delaminated with hydrochloric acid. The delaminated VMT was then added to the PVA solution with various mixing times. The structu… Show more
“…Two steps preparation, delamination with hydrochloric acid and then addition to the PVA solution using various mixing times. The positive effect of the vermiculite content on the thermal behavior of the PVA-vermiculite blends was observed [131].…”

“…It is very abundant and much cheaper in comparison with other clays such as montmorillonite, hectorite and saponite (Xu et al, 2003). It is an expandable 2:1 mineral and often forms from alteration of mica (Howe-Grant, 1992;Aristov et al, 2000).…”
“…VMT has been proved to be a nice reinforcement for the preparation of nanocomposites in our previous work [20,21]. However, there is no literature about the preparation of chitosan/ VMT nanocomposites.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
