Preparation and conductivities of fullerene-doped polyanilines

Abstract

Upon doping with C60–C70(75 : 25 by mole) or by C60(>99%) in N-methylpyrrolidin-2-one–toluene solution at room temperature, conductivities of the emeraldine base of polyaniline as free-standing solution-cast films were found to increase significantly toca. 10–4 S cm–1 at a fullerene content of ca. 1 mol%.
