We have synthesized water soluble Polypyrrole(Ppy) by using functional dopants [butylnaphthalene sulfonic acid sodium salt (NaBNS), di(2-ethylhexyl) sulfosuccinate sodium salt (NaDEHS), polystylenesulfonic acid (PSSA) etc. ] and it’s blends [Ppy + Polyaniline(PANI), Ppy + Polyethylene(3,4-dioxythiophene) (PEDOT)]. It showed an good solubility ( ＞ 4 wt%/vol.) in H2O, as well as showing the film conductivity of ~ 5 x 10-1 S/cm. The charge carrier mechanism of Ppy-DEHS/H2O, PANI/ H2O and PEDOT/ H2O films in accordance with the temperature change showed a typical 3D and 1D VRH model by σ = σ0 exp[-(T0/T)1/n+1] formula, a VRH model of Mott. |
