  • Publication number: 20070249803
    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.
    Type: Application

  • Publication number: 20060169954
    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.

  • Publication number: 20050062486
    Abstract: The present invention includes the use of conducting polymers as sensors in distributed sensing systems, as sensors and operating elements in multifunctional devices, and for conducting-polymer based multifunctional sensing fabrics suitable for monitoring humidity, breath, heart rate, blood (location of wounds), blood pressure, skin temperature, weight and movement, in a wearable, electronic embedded sensor system, as examples. A fabric comprising conducting polyaniline fibers that can be used to distribute energy for resistive heating as well as for sensing the fabric temperature is described as an example of a multifunctional sensing fabric.

  • Publication number: 20050037149
    Abstract: Immersion precipitation of solutions having 15%-30% (w/w) and various molecular weights of the emeraldine base form of polyaniline in polar aprotic solvents are shown to form integrally skinned asymmetric membranes and fibers having skin layers <1 ?m thick which exhibit improved rates of gas transport while preserving good selectivity. These membranes can be further transformed by an acid doping process after fabrication to achieve excellent permeation rates and high selectivities for particular gas separations. Prior to the use of concentrated EB solutions, the formation of integrally skinned asymmetric membranes was not possible, since films and fibers made from <5% w/w polyaniline solutions were found to disintegrate during the IP process.
