摘要: Abstract The effect of doping polyacrylonitrile (PAN) with iodine on the dielectical properties and ac conductivity as a function temperature frequency is investigated. Thermogravimetric analysis, TGA, FTIR measurements show that PAN undergoes degradation starting at 523 K. Doping I2 enhances electrical σac in range under investigation due to oligomerization nitrile groups giving conjugated polyimine. thermal activation energy, ΔE, calculated for PAN/I2 found be 0.16–1.16 eV 0.1 kHz. correlated barrier hopping (CBH) conduction mechanism dominant samples.
