  • Patent number: 6804105
    Abstract: A polymer material comprising channels whose temperature-independent conductivity exceeds 106 S/cm is used to form conductive films. Conduction takes place through threads and channels passing through the film which is otherwise a dielectric. The film is produced by first depositing a macromolecular polymer substance on a substrate. During preparation, the substance is preferably in a viscous liquid state. Stable free electrons (polarons) are then created by ionizing the substance. This is assisted by exposure to UV radiation and the presence of strong polar groups in the polymer. Various enrichment techniques, such as applying a strong electric field, are then used to join the superpolarons together into conductive threads within the medium. To stabilize the positions of the threads, the medium then may be solidified, preferably by cooling it below its glass transition point or inducing cross-linking between the macromolecules. The film may be a membrane.

  • Patent number: 5777292
    Abstract: A method is disclosed for producing a polymer material whose room temperature conductivity exceeds 10.sup.6 S/cm. In a preferred embodiment the material is produced in the form of a film having thickness less than 100 .mu.m. Conduction takes place through threads passing through the film which is otherwise a dielectric. The film is produced by first depositing a macromolecular polymer substance on a substrate. During preparation, the substance must be in a viscose liquid state. Stable free electrons (polarons) are then created by ionizing the substance. This is assisted by exposure to UV radiation and the presence of strong polar groups in the polymer. Various techniques, such as applying a strong electric field, are then used to join the polarons together into conducting threads within the medium. To stabilize the conductivity, the medium is then solidified by cooling it below its glassing point or inducing cross-linking between the macromolecules.
