Abstract
Nanocomposites Polyaniline/Maghnite clay (PANI-Mag) were synthesized by solution polymerization of aniline in the presence of sulfuric acid using potassium persulfate (PPS) as oxidant. Using molar ratio of monomer to oxidant of 2:1, the aniline was polymerized and largely incorporated into the Maghnite, which was confirmed by FTIR, 1H-NMR spectra and UV-Vis spectroscopy. These methods show the shifting of some peaks, 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
