    摘要： A linear electrochemical actuator is described where at least one electrically conductive (between 400 and 1000 S/cm), doped polyaniline solid fiber or a yarn produced from such fibers is disposed in an electrolyte inside of a electrically conductive polyaniline hollow fiber, thereby allowing 2-electrode operation without a metal backing. This is an example of the electrochemical devices of the present invention having a solid-in-hollow polymer fiber configuration. In a propylene carbonate electrolyte, the electrochemical and actuation behavior of the fibers was found to be influenced by the solubility and size of the polymer dopants. That is, solubility of the dopant in the electrolyte resulted in high electroactivity and strain in the fibers. Actuation of fibers was also affected by electrolyte anions, small anions resulting in anion-exchange dominated actuation, while large anions resulted in cation-exchange dominated actuation. Isotonic strains of 0.9% and isometric stresses of 0.9 MPa were realized for the solid-in-hollow polyaniline fiber actuators.

    摘要： Dopable, fully dense polymer membranes are used to form membranes having selective permeabilities. To improve selectivity, the membranes may be subjected to chemical or electrochemical treatment with electron donors or acceptors to alter the doping level of the polymer membrane, generally in a reversible fashion. This leads to significant changes in gas permeation rates relative to what is observed for the non-doped, fully dense polymers. This change in doping level of the polymer films can be precisely controlled by varying the concentration and nature of chemical dopants used. Desirable changes in permeation rates are achieved by a treatment which comprises a reversal doping of the polymeric material, followed by removal of the dopants (to provide an "undoped" polymer). Further addition of controlled amounts of at least one dopant species to the undoped polymer by a second, "redoping" procedure can still more dramatically change the permeability of large species, leading to particularly large separation factors.

    摘要： The present invention includes the preparation of highly conducting conjugated polymers and their use as electrochemical actuators, A typical electrochemical actuator comprises a highly conducting, conjugated polymer for the anode or the cathode, or for both the anode and the cathode; suitable conjugate polymers have a conductivity ≧100 S/cm. The material may have any form, including films and fibers. A preferred shape is a strip or a fiber, where the fiber can be solid or hollow, although any shape may be used. Before use, the material may be treated, for example, by immersion in an acid, in order to dope/protonate the material or to introduce anions or to exchange the anion in the polymer for another anion. Other materials may be incorporated in the polyaniline to increase its conductivity or to provide other benefits, such as increased strength. Useful conducting polymers include monomers of anilines, pyrroles, thiophenes, phenylene vinylenes, and derivatives thereof.
