Over the past 25 years, poly(3,4-ethylenedioxythiophene) (PEDOT) has appeared to be one of the most promising conducting polymers due to its high environmental stability, low band gap, and high conductivity. However, PEDOT has the intrinsic disadvantage because it is insoluble in common solvents. To overcome this problem, a novel water-soluble PEDOT is synthesized. (2-thiophene-2-yl-ethyl)-(4-vinylbenzyl)-amine (TVA) is synthesized as a grafting site of EDOT, and then poly(sodiumstyrenesulfonate-co-(2-thiophene-2-yl-ethyl)-(4-vinylbenzyl)-amine (P(SSNa-co-TVA)) precursor is synthesized by free radical polymerization. EDOT monomer is grafted onto the P(SSNa-co-TVA) backbone by chemical oxidative polymerization. In this manner, a water-soluble and self-doped conducting PEDOT graft copolymer (PSSA-g-PEDOT) is synthesized and its conductivity dependence on the number of grafting site and the grafting length is systematically investigated. |
