  • Publication number: 20090061228
    Abstract: The present invention relates to a method of preparing solid particulates and solid particulates prepared by using the method. The method of preparing solid particulates includes dissolving an organic or inorganic compound in a first solvent to provide an organic or inorganic compound-included solution, dispersing the organic or inorganic compound-included solution in a second solvent to provide an emulsion, and concentrating the emulsion in a dispersing medium to precipitate the organic or inorganic compound as solid particulates to provide a dispersion including the solid particulates. The first solvent is an organic solvent or an aqueous solvent, and the second solvent is an organic solvent or an aqueous solvent that is not compatible with the first solvent.

  • Patent number: 6248818
    Abstract: Disclosed are polythiophene-based conductive polymer liquid compositions of high conductivity and transparency. The compositions comprise 16-32 weight % of an aqueous polythiophene-based conductive polymer solution, 52-80 weight % of an alcohol solvent, 1-12 weight % of an amide solvent, 0.01-0.4 weight % of a sulfonic acid group-containing monomer dopant, and optionally 2-8 weight % of an alkoxysilane. The compositions can be applied to transparent substrates to form coatings which have a surface resistance of 1 k&OHgr;/□ or less and a transmittance of 92% or higher. With the excellent conductivity and transparency, the compositions are useful as electromagnetic wave-shielding materials, finding numerous applications in cathode ray tube screens (TV sets and computer monitors) as well as CPP films, polyethyleneterephthalate films, polycarbonate panels, and acryl panels.
