We have studied conductivity and molecular weight obtained poly(2-ethanolaniline), P2EANi. P2EANi synthesized according to the best ratio of obtained molar of initiator to monomer at different reaction times. Then we measured the mass and conductivity of the obtained polymers in the best time of polymerization. Next, we repeated these reactions under different electric fields in the most appropriate time and measured the mass and conductivity of obtained polymers. As a result, intensity of the required electric field for polymerization was determined. After which the polymerization was carried out at the best electric field at different times. Finally, the best time and amount of the electric field for polymerization were determined. Moreover, we studied the doping of polymerization in the presence of an electric field by applying different dopants and other initiators. Then compared the obtained results to the results of a similar condition; but without the electric field. As a result we found the best condition for the reaction was determined as follows; the P2EANi with a high molecular weight was synthesized under the electric field, Mw=193749 g/mol, with Mw/Mn=2.3. The conductivity of the black films oxidized by ammonium peroxydisulfate and doped with dodecylbenzene sulfonic acid cast from NMP was higher than 0.118 S/cm under 10 KV/Cm2 electric field and showed an enhanced resistance to aging. It can be concluded that polymers synthesized under electric field probably have better physical properties as a result of less branching and high electrical conductivity.
