Polyaniline is a conducting polymer synthesized through oxidative polymerization of aniline monomers, belonging to the family of intrinsically conductive polymers (ICPs). It is valued in electronics, sensing, and energy storage applications for its electrical conductivity, environmental stability, and tunable properties through doping. Engineers select polyaniline over passive polymers when electrical function is required without sacrificing processability, and over metals when lightweight, corrosion resistance, or solution-based manufacturing are priorities.
