Core–shell particles with conductive polymer cores

Abstract.

Heterocoagulation of large cationic polypyrrole particles with small anionic polyacrylate beads followed by heat processing of the heterocoagulate units proved to be an efficient method in the preparation of core–shell particles with conductive cores and dielectric shells. Specific conditions required for producing monodispersed composite particles with uniform shells were examined in the stages of the synthesis of polypyrrole particles with controlled size, in "one-step" heterocoagulation of oppositely charged polypyrrole microbeads with small polyacrylic particles, and during shell formation by spreading of the acrylic polymer on the surface of polypyrrole cores.
