Abstract :
Poly (o-toluidine) (POT) as an electrically conducting polymer, which is emerging as a promising synthetic metal. The POT is one of promised polymer because of used it in various area of applications such as Light Emitted Diode (LED), Filed Effect Transistor (FET), Solar Cell and Sensors. The Polymeric materials have many physical properties, which make them mostly used in microelectronic devices. Electrical conductivity of the polymer materials can be investigated either by the synthesis of a polymer of definite chemical structure. The principal use of POT worldwide is in the manufacture of dyestuffs, although it is also use in the production of rubber, chemicals also used as a corrosion inhibitor in paint formulations has limited uses in analytical laboratory procedures. Attention of many researchers is due to its ease of synthesis, processibility, good thermal stability and good environmental stability. In this work POT was prepare by chemical oxidation method in the presence of ammonium persulphate (APS) as an oxidizing agent. The process was carried out in an acidic medium (1M H2SO4). The Prepared conducing polymer was characterize by ultra violet-visible absorption spectroscopy (UV-Vis). The structure of the sample examined by X-ray diffraction (XRD) and Surface morphology determined by Scanning Electron Microscope (SEM). From this study, it is clear that Poly (o-toluidine) shows amorphous structure and shows similar behaviors of polyaniline.
