Polyaniline

Conductive Polymer for Anti-Corrosion Coatings and Sensors

Polyaniline (PANI) is a conductive polymer valued for its tunable  conductivity, environmental stability and versatility. It enables high-performance, sustainable applications in anti-corrosion coatings, sensors, and electromagnetic shielding. PANI-based coatings form passivating layers that cut corrosion by over 90% and extend metal lifespan in harsh conditions. Its redox activity and sensitivity to pH, gases, and biomolecules make it ideal for electrochemical sensing. Proven in large-scale tests across oil & gas, marine, and aerospace sectors, PANI enhances coating durability up to 5×, reduces maintenance, and supports green, cost-effective solutions.
