Poly(3,4-ethylenedioxythiophene) (PEDOT) aqueous dispersions were prepared by polymeric ionic liquids (PILs), poly(1-vinyl-3-ethylimidazolium bromide), poly(1-vinyl-3-tert-butylimidazolium bromide) and poly(1-vinyl-3-isopropylimidazolium bromide). By addition of various lithium salts, the PIL stabilizer becomes hydrophobic and precipitates in water and traps the PEDOT particles inside. After drying PEDOT / PIL complexes, the complexes were dispersed in organic solvents such as propylene carbonate and nitromethane. Observing AC and DC conductivity of PEDOT / PIL complexes, the conductivity were obtained as high as 0.01 S/cm |
