Thermal stability of electric conductivity of polypyrrole (PPy) was improved using aromatic sulfonate derivatives as dopants having mobile hydrogen in the form of acid groups such as sulfonic acid, carboxylic acid, or hydroxide groups. Particularly, when m-sulfobenzoic acid or 5-sulfosalicylic acid were used as dopants, the PPy showed high thermal stability of electric conductivity and kept 95% electric conductivity even after heating for 8h at 150 °C in air.
