Synthesis and Characterization of Poly (p-phenylenediamine) in the Presence of Sodium Dodecyl Sulfate

Abstract

Conducting polymers are cation salts of highly conjugated polymers and they are synthesized by electrochemical or chemical oxidation method. Chemical oxidative polymerization has formed various functional polymers. In the present work, the chemically oxidative polymerization of p-phenylenediamine and p-phenylenediamine with surfactant like Sodium Dodecyl Sulfate was prepared at room temperature. The synthesized polymers were characterized using spectroscopic techniques like IR, UV and it confirmed the formation of the polymer. The thermal properties with their stability were studied using TGA, DTA and DTG and it was confirmed that the polymers were stable up to 700°C which is also evident from the activation analysis calculation. The X-ray analysis confirms the crystalline nature of the polymer which is also confirmed from the Scanning electron microscopic analysis. The prepared polymers were of semiconducting in nature and has the fluorescence property.
