Synthesis of Polyaniline - Step by Step Procedure
Intrinsically conducting polymers (ICPs) are remarkable materials that exhibit electrical conductivities on par with metals, while maintaining the unique properties of polymers. Among conducting polymers, Polyaniline has gained a lot of interest due to its low cost and easy synthesis, multiple interchangeable electronic states, tunable conducting and optical properties, and high moisture stability. The most common and easy method of synthesizing conducting polymers is "Chemical Oxidative Polymerization", in which the monomer is mixed with an oxidizing agent and a suitable acid to give products. Now let's prepare one of the most easily synthesized conducting polymers aka Polyaniline by this method. Synthesis of Polyaniline Goal: The appearance of a dark green-colored product, indicating the formation of the conducting state of Polyaniline (Emeraldine Salt). Materials: Aniline: monomer, distilled before use for purification. Sul...
