Abstract Chemically synthesized poly(o-methoxyaniline) was dissolved in N-methyl pirrolidinone and cast in the form of flexible, free-standing films. The electrical properties of these films were investigated by ac conductivity measurements in the frequency range from 10 −2 to 10 5 Hz, as a function of the doping level and temperature. For high doping levels the conductivity is frequency independent. However, for low doping levels the conductivity increases significantly in the high frequency range. The results are discussed in terms of a hopping model based on a method of distribution of transition rates.
