    摘要： Polycrystalline materials containing crystallies of precursors to electrically conductive polymers and electrically conductive polymers are described which have an adjustable high degree of crystallinity. The intersticial regions between the crystallites contains amorphous material containing precursors to electrically conductive polymers and/or electrically conductive polymers. The degree of crystallinity is achieved by preparing the materials under conditions which provide a high degree of mobility to the polymer molecules permitting them to associate with one another to form a crystalline state. This is preferable achieved by including additives, such as plasticizers and diluents, to the solution from which the polycrystalline material is formed. The morphology of the polycrystalline material is adjustable to modify the properties of the material such as the degree of crystallinity, crystal grain size, glass transition temperature, thermal coefficient of expansion and degree of electrical conductivity. High levels of electrical conductivity are achieved in in the electrically conductive polycrystalline materials without stretch orienting the material. The enhanced electrical conductivity is isotropic as compared to a stretch oriented film which has isotropic electrical conductivity. In the preferred embodiment, additives are added to a solution containing a solvent and the precursor or electrically conductive polymer. The additives are preferably plasticizer or diluents. As the solvent is removed the material dries and contains a higher degree of crystallinity than in the absence of the additive.

    摘要翻译： 描述了具有可调节高结晶度的导电聚合物和导电聚合物的前体结晶的多晶材料。 微晶之间的区域包含含有导电聚合物和/或导电聚合物的前体的无定形材料。 通过在使聚合物分子彼此相互结合以形成结晶状态的聚合物分子提供高度迁移率的条件下制备材料来实现结晶度。 优选通过将诸如增塑剂和稀释剂的添加剂添加到形成多晶材料的溶液中来实现。 可以调节多晶材料的形态，以改变材料的性质，例如结晶度，晶粒尺寸，玻璃化转变温度，热膨胀系数和电导率。 在导电多晶材料中实现高水平的导电性而不使材料拉伸取向。 与具有各向同性导电性的拉伸取向膜相比，增强的导电性是各向同性的。 在优选的实施方案中，将添加剂加入到含有溶剂和前体或导电聚合物的溶液中。 添加剂优选为增塑剂或稀释剂。 当除去溶剂时，与没有添加剂相比，材料干燥并含有更高的结晶度。

    摘要： Structures containing conducting polymers and methods of fabrication thereof. Electrical conductivity can be induced in polymers selected from the group consisting of substituted and unsubstituted polyanilines, polypara­phenylenevinylenes, substituted and unsubstituted polythiophenes, substituted and unsubstituted poly-p-­phenylene sulfides, substituted polyfuranes, sub­stituted polypyrroles, substituted polyselenophenes, polyacetylenes formed from soluble precursors, com­binations thereof and blends thereof with other polymers. The polymer contains a doping precursor, selected from the group consisting of onium salts, iodonium salts, triflate salts, borate salts, tosylate salts and sulfonyloxyimides. Conductivity can be selectively induced in the polymer by selectively doping upon selective exposure to a source of energy such as electromagnetic radiation, an electron beam and heat. The electrically conductive polymers of the present invention are useful as electron discharge layers for electron beam applications, such as SEM observations, as electromagnetic interference coatings on dielectric surfaces and as an electron beam resist which acts as a discharge layer.
