摘要：

Nanocomposites of NiO and Ni(OH)(2) prepared by compaction of powders synthesized by rapid thermal decomposition of precursors in solution (RTDS) were characterized by impedance spectroscopy at room temperature. The marked decrease of resistivity with increasing humidity was attributed to an increase of the water phase and ionic transport therein. Electrical behavior was modeled in terms standard electrocomposite mixing laws.
