摘要：Oxidative chemical polymerization of 3,4-ethylenedioxythiophene was carried with 5.8-μm sulfonated polystyrene latex particles as template. Polymerization led to formation of poly(3,4-ethylenedioxythiophene) distributed over the surface of template particles. Increase in initial monomer concentration resulted in the change of poly(3,4-ethylenedioxythiophene) morphology from isolated clusters to continuous 0.2–0.5-μm-thick surface shells. Structure of poly(3,4-ethylenedioxythiophene) coatings had crucial influence on the surface charge and macroscopic electrical conductivity of composite latex particles.
