摘要：

The dc conductivity, dielectric constant, and electron spin resonance measurements have been performed on samples of polypyrrole, poly(N-methyl pyrrole-pyrrole), and poly(N-methyl pyrrole) having different BF4- concentrations in the temperature range 77-350 K. Different parameters evaluated from these measurements support the existence of Mott's variable range hopping mechanism in these systems. (C) 1997 American Institute of Physics.
