    • A processable electrically conductive polymeric complex comprising a polyelectrolyte having acid functional groups and a conductive polymer selected from the group consisting of polyaniline, polypyrrole, polythiophene, poly(phenylene sulfide), the conductive polymer ionically bound to the polyelectrolyte. The mole ratio of the monomers which form the conductive polymer to the acid functional groups of the polyelectrolyte is ≧1. The polymeric complex is made by a template-guided chemical polymerization process which comprises adsorbing the monomers onto the polyelectrolyte in a mixture of alcohol and water to form a polyectrolyte adduct, emulsifying the polyelectrolyte adduct in an acid to form an emulsified polyelectrolyte adduct and oxidatively polymerizing the emulsified polyectrolyte adduct. The polymeric complex is water insoluble when dried as a coating on a substrate.
    • 一种可加工的导电聚合物复合物,其包含具有酸官能团的聚电解质和选自聚苯胺,聚吡咯,聚噻吩,聚(苯硫醚),与聚电解质离子键合的导电聚合物的导电聚合物。 形成导电聚合物的单体与聚电解质的酸官能团的摩尔比为> = 1。 聚合物复合物通过模板引导的化学聚合方法制备,其包括将单体吸附在醇和水的混合物中的聚电解质上以形成多分散体加合物,在酸中乳化聚电解质加合物以形成乳化的聚电解质加合物和氧化聚合 乳化的多联体加成物。 当作为基材上的涂层干燥时,聚合物复合物是不溶于水的。

    • A compact full-range loudspeaker system includes an elongated enclosure having two open ends joined by a hollow interior, which enclosure may be of fixed dimension or telescoping, and has a full-range speaker mounted at each end of the cylindrical enclosure. The enclosure length is set in a range governed by the small speaker size to maximize the system response, particularly in the lower frequency range, and a dampening material is provided to construct the enclosure to minimize the structural acoustic response of the enclosure when being driven. A pair of miniature sound boards may be flat, polymer surfaces mounted to a base and positioned at each end of the cylindrical enclosure at an angle facing each speaker for reflecting sound waves emanating from the speaker in accordance with the positioning of the cylindrical enclosure to create an effective sound stage and control directionality.
    • 紧凑的全范围扬声器系统包括具有由中空内部连接的两个开放端的细长壳体,该外壳可以是固定尺寸或伸缩的,并且具有安装在圆柱形外壳的每个端部处的全范围扬声器。 机箱长度设置在由小扬声器尺寸控制的范围内,以最大化系统响应,特别是在较低频率范围内,并且提供阻尼材料以构造外壳,以最小化驱动时外壳的结构声响应。 一对微型声音板可以是平坦的,聚合物表面安装到基座并且以与每个扬声器相对的角度定位在圆柱形外壳的每个端部处,以根据圆柱形外壳的定位反射从扬声器发出的声波,以产生 有效的舞台和控制方向。
