Magnesium-aluminum (Mg-Al) based layered double hydroxide (LDH) polymer nanocomposites were developed through the implementation of a rehydration technique. Organic anionic surfactant sodium dodecyl sulfate (SDS) and an anionic polymer, poly(styrene sulfonate) (PSS) were used for intercalation in the cationic intergallery spacing of LDH. This rehydration technique was performed by calcination of the LDH precursor for removal of carbonate anion followed by rehydration of organic anionic phase in a nitrogen rich atmosphere. The resulting nanocomposites were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and powder x-ray diffraction (XRD).
