Properties of the Composites Made of Glauconite and Polyaniline in Aqueous Solutions of Phosphoric Acid
The glauconite-polyaniline composites were prepared through oxidation of aniline using ammonium peroxodisulfate in aqueous solutions of phosphoric acid on the surface of a glauconite powder. Intermolecular interaction between amorphous polyaniline macromolecules and interphase coupling of polyaniline to the glauconite surface was confirmed by X-ray diffraction and FT-IR spectroscopy. Higher concentration of phosphoric acid led to a stronger intermolecular and interphase connection because of H-bonding, and that resulted in higher electric conductivity while a magnetic susceptibility of the composites was not affected. Thermal analysis for the prepared composites confirmed the interfacial interaction between the polyaniline macromolecules and the surface of powdered glauconite.
