Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of NAUN Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Abstract: The electrical characteristics of hybrid polymer thin films consisting of conductive carbon black (CB) nanoparticles (0.1wt%) doped in poly(ethylene oxide) (PEO) filled with electrolyte potassium alum salt at varied concentrations were studied. For varied potassium alum concentrations and fixed content of conductive carbon black of concentration (0.1 wt. percent), the AC electrical characteristics were studied in the frequency range (3kHz - 5MHz) and temperature range (30 oC - 55 oC). Thin film physical constants such as dielectric constant, dielectric loss, AC conductivity, and impedance have been recorded. These measured amounts were discovered to fluctuate with potassium alum concentration, applied field frequency, and temperature. With increasing potassium alum content, frequency, and temperature, the AC conductivity (ac) increases. Dielectric constant (ε') and dielectric loss (ε'') of the composites increase with potassium alum concentration and decrease with frequency.
