摘要：

The electrical properties of Langmuir-Blodgett (LB) films of polypyrrole fabricated on a ferric stearate template have been studied, The LB films exhibit a highly organized two-dimensional linear array of polymer granules sandwiched between insulating fatty acid layers. Measured in-plane conductivity is as high as 1.25 S cm-1 whereas conductivity along the film normal is 10(-8) S cm-1, revealing a very high degree of anisotropy. A temperature dependence study suggests charge transport by one-dimensional variable range hopping.
