چکیده
|
Polymeric composites of iron chloride (fecl3) doped poly (ethylene oxide) fabricated in various weight fractions were subjected to ftir,ac impedance test,dc conductivity and resistivity respectively. ftir data confirms the complexation of fecl3. dc test and ac impedance results reveal that direct current (dc) carrying capacity and ionic conductivity of the fabricated composites increases with increasing fecl3 content,while reverse trend was observed for resistivity. the current findings are strongly supported by the decreasing trend in the energy band gap values for the fecl3 doped peo composites.
