On the physical and electrical properties of poly propenal prepared by electropolymerization technique Original Research Article

Electropolymerization of acrolein in an aprotic solution leads to the formation of a highly crosslinked homopolymer structure. The formed polymer was identified by elemental analysis and IR spectrum. Based on the proposed model, the chemical structure of the formed polymer is assigned. The investigated polymer is stable up to 114 °C with a thermal activation energy 0.72 eV. AC conductivity measurements, at different temperatures and frequencies, showed that the prepared polymer is a highly polarized material. The relaxation process is an Arrhenus type with activation energy 6.1 eV. The conduction behaviour of the formed polymer could be attributed to the quantum tunneling mechanism.
