Abstract: An electrically addressable release pad for use in a burst electrode drug release (delivery) system. The pad useable in this system comprises a polymer, preferably polypyrrole, which surrounds medicine. Once a section of the polymer receives an electrochemical potential sent from an electrode contained within the pad, a defined dose of medicine contained therein is released. The pad is designed to be worn by a patient, so that when the medication is released, its administered to the patient, without the patient having to do anything. The electrode typically can be a burst electrode, one with a unique electrical signature. The electrode can be triggered from a remote source.

Abstract: The invention herein comprises a polymer bilayer which eliminates the spontaneous release of an active molecule by ion exchange. The spontaneous release is slowed by the application of a second polymer layer to the top of the electroactive polymer. The electroactive bilayer is preferably polypyrrole. The second polymer layer is preferably poly(vinyl butyral), poly(vinyl acetate) or nafion. This second layer stops the spontaneous release of the active molecule. The active molecule will usually be a pharmaceutical agent or drug. This bilayer allows a more effective controlled drug delivery system wherein the quantities and timing of the drugs can be given to the human being/animal patient with a high degree of certainty and predictability.

Abstract: A process for the preparation of water soluble polypyrrole is provided. The process comprises admixing pyrrole, water, and an effective amount of an electroinactive water soluble polycation to form an initial composition. That initial composition is admixed with an effective amount of an oxidizer to form a reacting composition, which is allowed to react for a time sufficient until substantially no decrease in potential occurs, whereby the polypyrrole is formed.

Abstract: A burst electrode system is provided that comprises an electroactive polymer having thereon either a polyanionic or polycationic dopant, and a biologically active ingredient that is releasable from said electroactive polymer, whereby said burst electrode system exhibits a release profile greater in quantity and faster than a standard Faradaic profile. The biologically active ingredient preferably is a drug. The electroactive polymer preferably is a polypyrrole or a polypyrrole polyelectrolyte complex such as polypyrrole poly(styrene sulfonate), heparin or polyacrylic acid.

Abstract: A metal/polymer laminate having a corrosion resistant metal surface. The laminate includes a metal film having opposite surfaces, one of which is coated with a coating which contains an intrinsically conducting polymer which inhibits corrosion of the opposite surface of the metal film. The coating can also be bonded to a substrate such as a non-conducting polymer or a second metal film. When the coating is also bonded to a substrate, it forms an interlayer between the metal film and the substrate. The laminate serves to protect the metal surface from corrosion in acid, salt and alkaline corrosive environments.
