    摘要: 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, or tube, although other forms of thermoplastic and thermoset polymers can be used as the substrates for pretreatment using, most preferably, phosphonylation-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. In an alternative embodiment, metals such as gold or platinum are bonded to the chemically interactive surface of a preshaped thermoplastic or thermoset article.

    摘要: A polymeric composition for use in medicine includes a hydrophobic bioabsorbable polymer admixed with a hydrophilic liquid polymer wherein the polymeric composition undergoes macroscopic phase separation on contact with aqueous media. The polymeric composition optionally includes a medicinal agent. The polymeric composition may be deposited as a permeable, semipermeable or occlusive irregular mass, regular mass, film or foam over a suitable surface such viable body tissue. Bioabsorbable implants formed from the polymeric composition may assume a variety of three dimensional configurations such as planar, spherical, cylindrical, rectangular and polygonal.
