  • Publication number: 20060208231
    Abstract: Organic inherently conductive polymers, such as those based on polyaniline, polypyrrole and polythiophene, are formed in situ onto polymeric surfaces that are chemically activated to bond, ionically, the conductive polymers to the substrates. The polymeric substrate is preferably a preshaped or preformed thermoplastic film, fabric, tube, or a medical device for tissue repair regeneration and/or replacement, although other forms of thermoplastic and thermoset polymers can be used as the substrates for pretreatment using, most preferably, C-succinylation-based processes followed by exposure to an oxidatively polymerizable compound capable of forming an electrically conductive polymer. The resultant conductive surface imparts unique properties to the substrates and allows their use in antistatic clothing, surface conducting films for electronic components and the like, and electromagnetic interference shielding for civilian and military installations as well as implantable medical devices.
