This review first surveies the characteristics （chemical composition, structure, synthesis and intercalation properties） of layered double hydroxide （LDH）, alternaotely known as anionic clay or hydrotalcite-like compound, and then provides the production methods of some eco-nanomaterials using LDH. Usually, LDH is characterized by its easy preparation under mild conditions, formation of nano-sized plate-like particles and unique properties such as high anion exchange capacity and good biocompatibility. In addition, the delamination of LDH has been achieved recently by chemical techniques to produce LDH nanosheets. Based on these features, the production examples of functional organic-inorganic nanohybrids, polymer-inorganic nanocomposites, and new carrier materials of drug delivery system from LDH are reviewed together with the recent results of our LDH research works.
