Abstract: This invention relates to a polymer dispersed liquid crystal type light control body using a nickel deposited electrode or a nickel-chromium alloy deposited electrode instead of an existing indium tin oxide electrode, including: two electrode substrates having electrodes, and a light control layer formed between the two electrode substrates, wherein at least one of the two electrode substrates includes a nickel-based electrode. The light control body can exhibit superior near-infrared blocking effects in ON state, and can also manifest peel adhesion strength, pendulum hardness of a film, haze and contrast ratio adapted for commercial applications thereof, ultimately achieving energy saving performance due to heat ray blocking effects as well as cost reductions.

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 ° 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.
