A novel water-soluble and self-doped conducting hybrid copolymer: poly(4-oxybenzenesulfonic acid) phosphazene-g-poly(3,4-ethylenedioxythiophene)

A different approach is clearly necessary to overcome the solubility problem of poly(3,4-ethylenedioxythiophene). Here, a synthetic strategy was followed to synthesize PEDOT graft arms on a poly-aryloxyphosphazene platform, which is also carrying sulfonic acid co-substituents. It is found that the conductivity of the novel copolymers increases with an increase in the PEDOT level.
