摘要：

Dielectric and conductivity studies have been performed on poly(propylene glycol) with a molecular weight of 4000 complexed with 0.01 to 6 mol% AgCF3SO3. The highest conductivity value at 70 degrees C, 8 x 10(-5) S cm(-1) was obtained for 6 mol% AgCF3SO3. The equivalent conductivity, Lambda, plotted against AgCF3SO3 concentration shows a:minimum and a maximum, similar to that found in other salt-poly(propylene glycol) complexes. The dielectric relaxation studies reveal two loss peaks: a primary peak which may be attributed to ion pairs and a secondary, low intensity peak only visible at low salt concentrations, that is assumed to be due to a relaxation attributed to the polymer chain.
