TLDR
Layered double hydroxides (LDHs) have been investigated for many years as host materials for a range of anion exchange intercalation reactions as mentioned in this paper and have been used extensively as ion-exchange materials, catalysts, sorbents and halogen absorbers.Abstract:
Layered double hydroxides (LDHs) have been investigated for many years as host materials for a range of anion exchange intercalation reactions. In this role they have been used extensively as ion-exchange materials, catalysts, sorbents and halogen absorbers. More recently, there have been a tremendous number of new developments using these materials to store and deliver biologically active materials in vivo. Significant advances have been made recently on the characterisation of these materials, including structural studies and on the mechanism of intercalation using in situ techniques.read more

Structure and Dynamics of Polymer-Layered Silicate Nanocomposites
TL;DR: In this article, the static and dynamic properties of polymer-layered silicate nanocomposites are discussed in the context of polymers in confined media, and both the local and global dynamics of the polymer in the hybrids are dramatically different from those in the bulk.

Anion-exchange reactions of layered double hydroxides
TL;DR: In this article, a small equivalent area forces the alkyl chain compounds to point away from the interlamellar surfaces and to form monomolecular films of high regularity.
