Electrical Properties of PAN/PMMA Blends Doped with Lithium Salts
Polymer blended electrolytes of various concentrations of undoped PAN/PMMA (80/20, 75/25, 70/30, 65/35 and 60/40 wt%) and doped with lithium salts (LiCl, Li2SO4H2O, LiNO3, Li2CO3) at 20% wt have been prepared by the solution casting method using dimethylformamide as a solvent. The electric...

| description |
Polymer blended electrolytes of various concentrations of undoped PAN/PMMA (80/20, 75/25, 70/30, 65/35 and 60/40 wt%) and doped with lithium salts (LiCl, Li2SO4H2O, LiNO3, Li2CO3) at 20% wt have been prepared by the solution casting method using dimethylformamide as a solvent. The electrical conductivity has been carried out using an LCR meter. The results showed that the highest ionic conductivity was 2.80x10-7 (Ω.cm)-1 and 1.05x10-1 (Ω.cm)-1 at 100 kHz frequency at room temperature for undoped (60% PAN + 40% PMMA) and (80% PAN + 20% PMMA) doped with 20%wt Li2CO3 composite blends, respectively. It was found from the measurements of the A.C conductivity of undoped (PAN+PMMA) and doped with different lithium salts in the frequency range (1kHz-100kHz) that A.C conductivity follows empirical laws σa.c(ω)=Aωs, where (s) is (are) located between (0.501-2.054). The frequency-dependent dielectric constant at room temperature for various composites exhibited that because of interfacial space charge polarization, the dielectric constant has a large value. The fluctuation of dielectric loss with the addition of various kinds of lithium salts and frequency-dependent dielectric loss were shown and discussed.
