    • 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.
    • 公开了具有高导电性和透明性的聚噻吩基导电聚合物液体组合物。 组合物包含16-32重量%的聚噻吩基导电聚合物水溶液,52-80重量%的醇溶剂,1-12重量%的酰胺溶剂,0.01-0.4重量%的含磺酸基 单体掺杂剂和任选的2-8重量%的烷氧基硅烷。 该组合物可以应用于透明基材以形成表面电阻为1kOMEGA /平方或更小,透光率为92%或更高的涂层。 具有优异的导电性和透明度,该组合物可用作电磁波屏蔽材料,在阴极射线管屏幕(电视机和计算机显示器)以及CPP膜,聚对苯二甲酸乙二醇酯膜,聚碳酸酯板和丙烯酸板中得到广泛应用。
