Patent number: 6399675Abstract: 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 ° 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.Type: GrantFiled: March 21, 2001Date of Patent: June 4, 2002Assignee: Q-Sys Co., Ltd.Inventors: Yang-Bae Kim, Chan-Ho Park, Jin-Who Hong
