Synthesis of PEDOT nanoparticles and vesicles by dispersion polymerization in alcoholic media

摘要

The synthesis of PEDOT nanoparticles and vesicles by dispersion polymerization in a methanol/water mixture (3/2, v/v) is reported, using either ammonium persulfate or iron(III) p-toluenesulfonate as oxidants and alpha-EDOT-PEO as a reactive stabilizer. The influence of the oxidant as well as the alpha-EDOT-PEO molar mass and concentration on the core-shell particle morphology and conductivity properties have been investigated. PEDOT particles with conductivities up to 1.5 x 10(-2) S . cm(-1) have been obtained in high yield.
