摘要：

Through magnetic-susceptibility measurements on samples of thermally aged polyaniline in the emeraldine-base form, Pauli and Curie susceptibilities are shown to depend sensitively on the presence of moisture. It is suggested that the same spin can contribute either to the Pauli susceptibility or Curie susceptibility depending upon its environment, or temperature, and that the presence of water even in trace amounts may determine the dynamical behavior of the spins.
