Abstract
Official abstract text for this publication.
An interpenetrating network (IPN) polymer membrane material includes a soft polyurethane interspersed with a crosslinked conducting polymer. The material can be reversibly “switched” between its oxidized and reduced states by the application of a small voltage, ˜1 to 4 volts, thus modulating its diffusivity.
First claim
Opening claim text (preview).
What is claimed is: 1. A fabric comprising an interpenetrating polymer network comprising net-poly(3-{2-[2-(2-{2-[(thiophene-3-carbonyl)-amino]-ethoxy}-ethoxy)-ethoxy]-ethoxy}-propane-1-sulfonic acid)-co-5, 5 bis-3,4 ethylenedioxythiophene-co-hydroxymethyl-3,4 ethylenedioxythiophene-co-(net-(poly(propylene glycol-tolylene 2,4 diisocyanate)))-ipn-(polyurethane). 2. A construction of fabric, wherein the construction is a protective garment, a filter, or a shelter and the fabric comprises an interpenetrating polymer network comprising poly(3-{2-[2-(2-{2-[(thiophene-3-carbonyl)-amino]-ethoxy}-ethoxy)-ethoxy]-ethoxy}-propane-1-sulfonic acid)-co-5, 5 bis-3,4 ethylenedioxythiophene-co-hydroxymethyl-3,4 ethylenedioxythiophene-co-(net-(poly(propylene glycol-tolylene 2,4 diisocyanate)))-ipn-(polyurethane).
