Abstract:
Provided are a conducting polymer film composition comprising a graft copolymer of a self-doped conducting polymer and an organic opto-electronic device comprising a conducting polymer film formed of the above-mentioned composition. In the graft copolymer of the conducting polymer contained in the composition in accordance with the present invention, the conducting polymer and polyacid are connected to each other via chemical binding. Therefore, application of the composition in accordance with the present invention to the organic opto-electronic device does not cause dedoping occurring from heat generated inside the device. As a result, the present invention enables an improvement in efficiency and life-time of the organic opto-electronic device.
Abstract:
Enediyne compounds of the formula: (1) characterized in that the structure thereof is very simple and the production process is easy, and that the molecular length thereof is shorter than those of compounds having been proposed. Consequently, electrode assemblies comprising any of these enediyne compounds are highly promising in the application to nanomolecular wiring (nanomolecular wire) whose production has been difficult.
Abstract:
A conductive organic thin film which is made up of organic molecules each having at one end a terminal bonding group bonded to a substrate surface by covalent bonding and having a conjugated bondgroup which is present anywhere in the organic molecule and has been polymerized with other molecules and a photoresponsive functional group which contains no active hydrogen atom and is present anywhere between the terminal bonding group and the conjugated bond group, the organic molecules being oriented and the conjugated bond groups having been polymerized to form a conductive network. The conductive organic thin film has such a light switch function that the conductivity changes upon irradiation.
Abstract:
Disclosed are composite compositions, comprising a conductive matrix and an electrochemically active polymer, which are useful as heterogeneous catalysts or charge- storage materials. Suitable electrochemically active polymers include redox polymers, such as polyvinylferrocene, and conducting polymers, such as polypyrrole, and interpenetrating networks containing both redox polymers and conducting polymers.
Abstract:
Described herein are polymer formulations for facilitating electrical stimulation of nasal or sinus tissue. The polymer formulations may be hydrogels that are prepared by a UV cross-linking process. The hydrogels may be included as a component of nasal stimulator devices that electrically stimulate the lacrimal gland to improve tear production and treat dry eye. Additionally, devices and methods for manufacturing the nasal stimulators, including shaping of the hydrogel, are described herein.
Abstract:
A Polymer having an acid number greater than 100 has a valent metal ion which is bonded to at least one reactive group. The characteristics of the Polymer include, conductivities of 4 S/cm to 200 S/cm or more, depending upon the concentration and nature of the metal bound, conductivities proportional to the amount of metal bound, the ability of the Polymer to bind metals having a +1, +2, +3, +4, or +5 valence charge to the Polymer, and the ability to bind two or more different metals to separate binding sites on the Polymer.
Abstract:
A biphasic material and devices comprising the same are provided for the development of conductive conduits that may be used for the treatment of peripheral nerve injury. These devices or conduits are designed such that repeated electric field gradients can be initiated to promote neurite and axonal outgrowth. Conducting conduits using doped synthetic and/or natural polymers create specifically patterned high and low conducting segmented materials, which are mechanically used to produce the electrical properties needed for nerve conduits. These electrical properties stimulate neurite outgrowth and axonal repair following a peripheral nerve transection.
