Abstract

Disclosed are electrically conductive microgel and preparation thereof. The electrically conductive microgel is prepared by adding 3 to 30 weight % of a monomer for synthesizing electrically conductive polymer and 1 to 20 weight % of a dopant to 15 to 80 weight % of an organic solution containing 5 to 60 weight % of microgel particles and polymerizing said monomer at a temperature of 0 to 80 .degree. C. under the addition of 2 to 40 weight % of an aqueous solution containing 1 to 40 weight % of an oxidative polymerization catalyst, in which the polymer adsorbed on the surface of the microgel particles. The electrically conductive microgel takes a core/shell structure in which electrically conductive polymers or oligomers are physically adsorbed onto the internal crosslinked microgel particles. With a three-dimensional array of the electrically conductive polymers or oligomers, the microgel shows excellent electrical functions, including electrical conduction, electromagnetic-radio frequency interference shielding, and electrostatic prevention, in spite of its low content of electrically conductive polymers.
