摘要: Composites of polymer electrolyte polyethylene oxide (PEO) complexed with NH4ClO4, (PEO:NH4ClO4), having different weight ratios dispersed semiconductor CuS (0–5 wt.%) have been prepared and characterized. The dispersal was achieved by its in situ formation the viscous solution (PEO:NH4ClO4) sulfuration CuSO4 using H2S. band gap composites found to be ~2.4 eV, which is higher than that bulk for it 2.2 eV. Scanning electron microscopy studies show particle size varies from ~200 nm several hundreds nanometers. Polarization composite so obtained has mixed ionic electronic conduction. Detailed I–V dispersoid a p-type semiconductor.
