Solid-In-Hollow Polymer Fiber Electrochemical Devices

View page
US Patent:
7288871, Oct 30, 2007
Filed:
Jul 6, 2004
Appl. No.:
10/886001
Inventors:
Wen Lu - Santa Fe NM, US
Elisabeth Smela - Silver Spring MD, US
Phillip N. Adams - Albuquerque NM, US
Guido Zuccarello - Silver Spring MD, US
Benjamin R. Mattes - Santa Fe NM, US
Assignee:
Santa Fe Science and Technology, Inc. - Santa Fe NM
International Classification:
H02N 11/00
B32B 23/00
US Classification:
310300, 428393, 428373, 428375
Abstract:
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.

US Patent:
20060169954, Aug 3, 2006
Filed:
Aug 19, 2005
Appl. No.:
11/208024
Inventors:
Elisabeth Smela - Silver Spring MD, US
Benjamin Mattes - Santa Fe NM, US
Philip Adams - Santa Fe NM, US
Guido Zuccarello - Silver Spring MD, US
Wen Lu - Santa Fe NM, US
International Classification:
H01B 1/12
US Classification:
252500000, 310800000
Abstract:
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.

20070249803, Oct 25, 2007
Filed:
Apr 28, 2004
Appl. No.:
11/568507
Inventors:
Benjamin Mattes - Santa Fe NM, US
Russell Goering - Santa Fe NM, US
Phillip Adams - Albuquerque NM, US
Guido Zuccarello - Silver Spring MD, US
Assignee:
SANTA FE SCIENCE AND TECHNOLOGY, INC. - Santa Fe NM
International Classification:
C08G 73/00
US Classification:
528422000
Abstract:
Methods are described for preparing substantially defect-free, adjustable molecular-weight, aniline-based polymers at sub-freezing temperatures in the absence of salts effective for lowering the freezing point of the reacting solutions, and in the absence of inorganic acids containing chlorine atoms.
