An improved method, based on mechanical stirring and a controlled solvent evaporation process, is proposed to obtain PANI(CSA) 0.5 / m ‐cresol solutions, which lead to gels with conductivities in the range 3 to 150 S/cm, preserving the elasticity associated to the gel network. Such high conductivity values have only been found for brittle films cast from PANI solutions. According to our experimental results, there is no justification for an analogy between the elastic modulus and the conductivity of physical networks.
