摘要：
A specially designed coaxial ESR cell capable of simultaneous ESR-electrochemistry-conductance measurements at variable temperatures was used to study conducting polymers. According to the temperature dependence of ESR intensity of polyaniline at controlled potential it is concluded that the spin nature changes from typical Curie at low potential (low conductivity) to typical Pauli at high potential (maximum conductivity) in strong support of the polaron lattice model.
