Polyaniline is dissolved in methyl pyrrolidone, and the resulting solution is cast onto substrates such as glass, plastic, and metal. The solvent is slowly evaporated at 60-80°C to produce a large-area support film with excellent mechanical and electrical properties. The tensile strength, Young's modulus, and elongation at break are 88, 1560, and 10%, respectively. After doping with hydrochloric acid, the strength decreases slightly, but the toughness increases, with an elongation at break reaching 58%.
