Abstract: A novel nanostructured poly (m-toluidine-co-3- aminobenzoic acid) copolymer has been prepared using dodecylbenzenesulphonic acid as surfactant and ammonium persulphate as oxidant at different monomer concentrations. The synthesized copolymer was soluble in solventslike DMSO, NMP, DMF and THF. The copolymers were subjected various analytical characterization methods such as electronic spectroscopy, FTIR spectroscopy, X-ray diffraction method, scanning electron microscopy and electrical conductivity. The UV-visible spectra reveals the π – π* and n-π* transitions at 313 nm and 517 nm respectively. FTIR absorption bands confirm benzenoid and quinoid rings in the copolymer chain. The X-ray diffraction study reveals that the copolymer is amorphous in nature. The DC electroactive nature of the copolymer is found to be 10-9 to 10-10 S/cm. The synthesized copolymer will show a change in resistance when exposed to the humidity and ammonia vapor sensors.
