Polyaniline: Synthesis, properties, and application

The methods of synthesis and the properties of polyaniline—a representative of the family of conducting polymers—are reviewed briefly. It is shown that variation in the conditions of aniline polymerization makes it possible to synthesize polymer materials with the desired structures and properties and, thus, to provide for the use of polyaniline in various fields of science and engineering. Special attention is given to the matrix synthesis of polyaniline as the main approach to obtain electroactive and conducting composite materials. The use of polyaniline and the related composite materials in polymer electronics is analyzed briefly.
