Polyaniline (emeraldine salt) (PANI-EB) is a conductive polymer which consists of a ring structure attached with nitrogen substituted derivatives. It forms a blend with nylon as a substrate. The composite has a high dye absorption capacity with good thermo-mechanical properties. It has an emeraldine type oxidation state that exists in the form of its salt.PANI-EB finds its usage in a variety of applications which include chemical sensors, absorptive micro-extraction, anticorrosive layer and microelectromechanical systems.Light colored conductive additive for thermoplastics and thermosets. Polyaniline-based organic and inorganic composites may be fabricated.,5 PANI may be used to prepare sensors for volatile organic compounds.
