Abstract

Conducting polymeric materials containing conjugated bonds has gained much focus in scientific and technological areas in recent years. The unique optical, electrical and chemical properties of these materials find their use in electronic displays, telecommunication, biosensors, anti-corrosion coatings, etc. Compared to polyaniline, poly ortho toluidine has attracted considerable attention, since they exhibit better solubility in a wide range of solvents. In this work, poly ortho toluidine (POT) has been synthesized by Chemical oxidative polymerization technique by using sulfuric acid as a protonation agent and ammonium peroxo disulfate (APS) as an oxidizing agent. The optical, structural and morphological properties and the size of the particles have been investigated. X-ray diffraction has shown that POT was a partially crystalline polymer due to doping of highly concentrated sulfuric acid. A flake-like feature was observed via scanning electron micrograph (SEM). The better protonation effect of POT was indicated by UV spectroscopy. The chemical structure of POT was investigated by FT-IR. Nanoparticle size analysis has revealed that the particle size was below 100 nm.
