Enhancing the electrical conductivity of aromatic polyamids via insertion of AZO group in the main chain

الملخص EN

New aromatic polyamides have been prepared through copolymerization of a terrazzo molecule with terephthalic acid.

Electrical conductivity measurements of the pure polymers show an enhancement of the electrical conductivity with increasing the AZO moieties in the backbone of the polymer.

The results can be rationalized by the effect of the dipole moment of the AZO group.

Doping effect with iodine was also studied.

The conductivity of the investigated polymers was increased by many orders of magnitude through the doping process.

The study proved that the alignment of the dipole moment of the groups along the polymeric chain will give another reason for enhancing the electrical conductivity of the polymers.
