The ESR single and magnetic properties of free standing film of polyaniline (PANI) have been measured as a function of elongation treatment and the protonation state. The results obtained are compared with its powder. The magnetic properties of free standing film of PANI is similar to its powder, and it varies with transition of insulator to metal after protonation. For elongated free standing film of PANI, on the other hand,both Pauli and Curie spin are higher than that of its powder and the free standing film this may be due to increasing of interaction between uncoupled electrons on quinoid ring at PANI chain.
