Abstract
Poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) with various PSS composition ratios (α) was synthesized by oxidative polymerization and particle size distribution and zeta potential of the resulting colloidal gel particles were investigated by means of a dynamic light scattering technique. It was found that mean volume diameter of the PEDOT/PSS colloidal gel particles were 400-600 nm at α = 1~6, which drastically decreased to ~10 nm at α = 8~15. On the other hand, zeta potential was about -80 mV regardless of the composition ratio. The electrical conductivity of the PEDOT/PSS cast film measured by a four-point method attained as high as 263 S/cm at α = 3.
