Introduction Layered-silicate based polymer nanocomposites have become an attractive set of organic-inorganic materials not only for their obvious potential as technological materials, but also for providing a convenient macroscopic system to study fundamental scientific issues concerning confined polymers [1]. Studying the formation, structure and dynamics of these nanocomposites can lead to a...

Iron-based layered double hydroxides (LDHs) obey to the general chemical formula [MII(1-x)MIIIx(OH)2]x+. [(x/n) An-, m H2O]xand contain a minimum of 50 % of iron, i.e. FeII or FeIII, in the cationic sheets. As LDHs contain FeII species, these are interesting minerals for several applications such as the reduction of anionic pollutants or the degradation of organic pollutants. They are mostly pr...
