Physico‐Chemical Properties of Laponite®/Polyethylene‐oxide Based Composites

Abstract

AbstractThis review aims to provide a literature overview as well as the authors’ personal account to the studies of Laponite® (Lap)/Polyethylene‐oxide (PEO) based composite materials and their applications. These composites can be prepared over a wide range of their mutual concentrations, they are highly water soluble, and have many useful physico‐chemical properties. To the readers’ convenience, the contents are subdivided into different sections, related with consideration of PEO properties and its solubility in water, behavior of Lap systems(structure of Lap‐platelets, properties of aqueous dispersions of Lap and aging effects in them), analyzing ofproperties LAP/PEO systems, Lap platelets‐PEO interactions, adsorption mechanisms, aging effects, aggregation and electrokinetic properties. The different applications of Lap/PEO composites are reviewed. These applications include Lap/PEO based electrolytes for lithium polymer batteries, electrospun nanofibers, environmental, biomedical and biotechnology engineering. Both Lap and PEO are highly biocompatible with living systems and they are non‐toxic, non‐yellowing, and non‐inflammable. Medical applications of Lap/PEO composites in bio‐sensing, tissue engineering, drug delivery, cell proliferation, and wound dressings are also discussed.
