Zn/Al-layer double hydroxides (Zn/Al-LDHs) with 2:1 Zn/Al ratio was prepared by heterocoagulation and modified using different anionic surfactants e.g, sodium dodecyl sulfate (DS) and sodium dodecyl benzene sulfonate (DBS), nitrates in the interlameller space of LDHs was exchanged through excellent anion exchange capacity by DS and DBS. Both hydrophilic and hydrophobized Zn-Al layered double hydroxide were applied as inorganic filler in free emulsion polymerization of aniline monomer. The morphology of the LDHs as well as the prepared nanocomposites was characterized by transmission electron microscope (TEM) and scanning electron microscope (SEM). The X-Ray diffraction (XRD) confirmed the formation of LDHs and totally delaminated into the polymer matrix. The thermal properties were studied by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Furthermore, the surface area of the prepared nanocomposites were investigated by BET and increased by addition of LDHs compared by neat polyaniline. The electrical conductivity of the prepared nanocomposites was investigated by increasing the ratio of LDHs in the nanocomposite. This work deals with potential applications of these materials, including ion exchange/adsorption, electrochemistry, UV production and conductive coating.
