“…PAN has been used for electrode of light emitting diode [4], Li ion rechargeable battery [5] and corrosion protection [6].Among organic-inorganic nano-composite-sites, PANIMag nanocomposites are the most prevalent and interesting due to the special properties as well as wide uses of polyaniline [7], the nature, abundance, low cost of Mag and attractive features such as a large surface area and ionexchange properties [8]. Clay minerals especially the members of smectite group are the most suitable candidates for synthesis of polymer nano-composites, because these possess a unique structure and reactivity together with high strength.…”

The nanocomposites namely Polyaniline/Maghnite clay (PANI-Mag) composites were synthesized by solution polymerization of aniline in the presence of sulfuric acid and amount of potassium persulfate (PPS), with molar ratio of monomer to oxidant of 2:1, the aniline was polymerized and largely incorporated into the Maghnite,which was confirmed by FTIR ,HNMR spectra and UV-Vis spectroscopy shows some peaks shifts, which indicate the formation of some new bonds and support the intercalation of PANI chains into the interlayer spacing of Maghnite MMT clay. That, the morphology of the PANI-Mag composites changed according to the proportion of clay. The conductive emeraldine salt form of polyaniline PANI-ES is inserted into the layers of maghnite clay to produce the hybrid with high conductivity and solubility in various organic solvents. The resulting organic-inorganic hybrid material, PANI-Mag has been characterized by various physicochemical techniques.

In this work synthesis & characterization of composite materials based on montmo rillonite (MMT) clay and intrinsically conducting polyaniline (PANI) is studied. The MMT type of clay used is locally available in the region which was used after chemical act ivation. The main thrust of this work was to know the possibility of usage of locally availab le clay to synthesise novel nanocomposites. Synthesises of PANI and processing and treatment of this clay was carried out in the lab by the authors. PANI was successfully incorporated into MMT to form PANI-MMT nanocomposites. The resulting organic-inorganic hybrid material, PA NI-MMT has been characterized by various physicochemical techniques. Formation of PANI inside the clay tactoid has been confirmed by X -ray d iffraction studies. Infrared spectroscopy studies reveal the presence of physicochemical interaction, probably hydrogen bonding, between clay and polyaniline. One of the main tec hnological applications of conducting polymers, particularly PANI, is in the area of corrosion protection of active metals. PANI-MMT nanocomposites synthesized using the present method is generally used to protect steel surface against corr osion.

“…Thus, the interlayer spacing can be modified, depending on the cation intercalated. Taking profit of the swelling of the montmorillonite when it is immersed in water, that produces a remarkable increase of the interlayer spacing [24], Yoshimoto et al explored the mechanochemical intercalation of different anilinium salts (chloride, fluoride and sulphate) into sodium montmorillonite layers prior to the polymerization [12,13,19]. They concluded that nanocomposites made using a solvent-free mechanochemical method, produced much more polyaniline between the montmorillonite layers than that obtained by conventional solution methods.…”
