Abstract:
This chapter deals with the preparative methods, structural aspects and chemical–physical characteristics of hydrotalcite-like compounds (HTlc), an emerging class of layered solids with anion exchange and intercalation properties. Biocompatible HTlc can be modified with molecular anions having pharmaceutical, antimicrobial or antioxidant activity to obtain materials that can release the active anions in different environments with a de-intercalation process. Moreover, the organic–inorganic hybrids can exfoliate when dispersed in polymeric matrices and act as active fillers ...
