Manifestation of MnCl2 fillers incorporated into the polymer matrices in their dielectric properties

Polyethyl methacrylate (PEMA) films filled with different mass fractions of MnCl2 were prepared using a casting method. The structural and electrical properties were studied. The filling content dependence of certain IR absorption bands was correlated with the obtained physical parameter characterizing the other properties. DC electrical resistivity (ρ) was measured in the temperature range 340–420 K for PEMA films filled with MnCl2 fillers. An intrachain one-dimensional interpolaron hopping mechanism was assumed to interpret the electrical conduction. AC conductivity behavior of all the prepared samples was investigated over the frequency range (42–5M) Hz and under different isothermal stablilization in the temperature range 300–423 K. It suggested that the hopping mechanism might be playing an important role in the conduction process, in low temperature regime. The values of σ0, A, and S satisfying the suitable fit of the conductivity data, as well as the corresponding (σDC).
