Polyaniline (PANI) was synthesized chemically in an acidic medium in the presence of ammonium persulfate (APS) as an oxidizing agent. PANI/montmorillonite nano-composites were prepared in the presence of various amounts of modified clay (from 1 to 5 wt.%) by solution casting method. | Investigation of physical and mechanical properties of polyaniline MMT nanocomposites Current Chemistry Letters 6 2017 151 158 Contents lists available at GrowingScience Current Chemistry Letters homepage www.GrowingScience.com Investigation of physical and mechanical properties of polyaniline MMT nanocomposites Hamid Gholami Alireza Shakeri and Vahid Saadattalab School of Chemistry College of Science University of Tehran 3174878564 Tehran Tehran Iran CHRONICLE ABSTRACT Article history Polyaniline PANI was synthesized chemically in an acidic medium in the presence of Received March 2 2017 ammonium persulfate APS as an oxidizing agent. PANI montmorillonite nano-composites Received in revised form were prepared in the presence of various amounts of modified clay from 1 to 5 wt. by June 20 2017 solution casting method. The free standing film of polyaniline and PANI clay nano-composites Accepted June 26 2017 was obtained by vaporization of solvent contain. Products were characterized by FT-IR spectra Available online SEM image and XRD pattern. Thermal stability was also studied by TGA analysis electrical June 26 2017 conductivity was measured by four point probe technique and mechanical properties were Keywords studied by tensile strength. The PANI clay nano-composites thermal and mechanical properties Polyaniline Montmorillonite were observed to be remarkably improved. For example polyaniline containing nano-clay has Nanocomposites less weight loss compared to pure polyaniline. In addition Young s modulus and strength at Physical and mechanical break point was increased in the case of polyaniline containing nano-clay The importance of properties our work is to provide a narrow look on the thermal and physical properties of polyaniline by the incorporation of montmorillonite into its structure as well as investigation of the conductivity of PANI MMT nanocomposites as a potential conductive polymer to be used in solar cells or have corrosion protection applications. .
