ABSTRACT:
Composite conducting polymer particles are described, wherein surface-treated supporting polymer particles having a charged surface of a first polarity are provided with a coating of conducting polymer of opposite polarity applied to the surface thereof. Suitably, the supporting insulating polymer particles are subjected to a surface treatment which introduces charged moieties thereon. The conducting polymer may be doped with at least one dopant to improve its conductivity. The novel particles have desirable rheological properties, and particularly when admixed with at least one processible polymer may be used to prepare products comprising conductive polymers in a particularly facile manner.
