Aligned arrays of binary nanoparticles of silver and silver oxide, respectively, with mean diameters of 8.5 nm have been prepared within a polymethylmethacrylate film. The alignment along an electric-field direction has been achieved by applying an electric field of ∼10 V/mm at frequency ranging from 1 kHz to 1 MHz. This behavior has been explained as arising due to a dipole-dipole interaction between the metal and oxide nanoparticles, respectively. The electrical resistivity is shown to arise due to variable range hopping mechanism. These nanocomposites exhibit three orders of magnitude resistivity changes as the relative humidity is varied from 35% to 95%. [ABSTRACT FROM AUTHOR] |
