Abstract: Films containing oriented dye, methods of manufacturing such films, and polarizers and liquid crystal display devices utilizing the films are disclosed. The film contains at least one dichroic dye which is uniaxially oriented. A film has a thickness of not less than 1 nanometer and not greater than 5 micrometer and contains the dichroic dye of not less than 1 percent by weight and not greater than 100 percent by weight. The film has a peak of absorption at 400 nm through 800 nm and a dichroic ratio of not less than 25 at the peak of absorption. The film may include a micro-pattern having a minimum width in a film plane of not less than 1 micrometer and not greater than 200 micrometer. In such a case, the dichroic dye has a dichroic ratio of not less than 10 at the peak of absorption. A method of manufacturing such a film according to the invention includes the step of forming a dye-containing film on a substrate having a fluororesin alignment layer on the surface thereof.

Abstract: Compositions are disclosed comprising electrically conducting polyaniline and particular substituted aromatic compounds that simultaneously form hydrogen bonds and ring-ring interactions with, respectively, the NH-groups and the six-membered rings of the conducting polyanilines. The present conducting polyaniline compositions show drastically enhanced processibility and their blends with insulating or semiconducting materials exhibit significantly improved electrical properties.

Abstract: Polyanilines are provided that are soluble and that form crystaline solids upon precipitation. The solid polyanilines are electrically conductive, soluble, and can be fabricated into various shaped articles for use in, for example, batteries, electrodes, photovoltaic cells, semi-conductor devices and the like.

Abstract: Compositions and methods are described that relate to the use of reaction products of metal compounds and protonic acids for plasticizing and neutralizing acidic, protonated compositions comprising substituted and unsubstituted polyanilines and co-polymers and or mixtures thereof; and for reducing the percolation threshold for conductivity in blends with insulating bulk polymers.
