Abstract
This paper reports on the synthesis and characterization of poly(2-methylaniline), PmA, a derivative of a very fascinating electronically conducting polymer polyaniline. PmA was synthesized in its salt form by one pot emulsion polymerization route using DBSA and sulfuric acid as co-dopants. Fourier transform infrared spectroscopy and Ultraviolet visible spectroscopic analysis confirmed formation of conducting emeraldine salt form of PmA. These PmA salts showed good redox reversibility and high purity. Thermogravimetric analysis revealed very good thermal stability up to 520 °C which is the highest reported thermal stability for PmA so far. Potentiodynamic polarization measurements clearly revealed that the PmA acts as corrosion protective coating on stainless steel with the protection efficiency of 55.59%.
