An organic-inorganic hybrid composite which comprises an inorganic component and an organic conducting component. The inorganic component inhibits deprotonation of the organic conducting component when the composite is exposed to a medium having a pH which would deprotonate the organic conducting component but for the presence of the inorganic component.

Conductive polymer-inorganic hybrid composites

A separation system comprising a stationary phase, a double stranded conductive polymer system contacting the stationary phase and means to place a mobile phase carrying a component to be separated from the mobile into contacting relationship with the polymer system whereby the component is captured by the polymer. The double stranded polymer is comprised of a -conjugated polymer and a polyelectrolyte.

Chromatographic and electrophoretic separation of chemicals using electrically conductive polymers

A electrically conductive polymeric composition comprising a plurality of polymeric complexes. Each polymeric complex comprises a strand of a &pgr;-conjugated polymer and strand of a polyelectrolyte. The polyelectrolyte is non-covalently bond to the &pgr;-conjugated polymer and has at least one reactive functional group that facilitates cross-linkage between the polymeric complexes when the polymeric complexes are heated.

Functionalized and processable conducting polymers

A coating composition which contains a polymeric complex between polyaniline and a polymeric ion. In addition to the said polymeric complex, the composition contains a water-dispersable binder. The composition is useful as a water-borne paint to be applied onto a metal substrate electrophoretically or non-electrophoretically.

Water-borne polymeric complex and anti-corrosive composition

A processable electrically conductive polymeric complex comprising a polyelectrolyte having acid functional groups and a conductive polymer selected from the group consisting of polyaniline, polypyrrole, polythiophene, poly(phenylene sulfide), the conductive polymer ionically bound to the polyelectrolyte. The mole ratio of the monomers which form the conductive polymer to the acid functional groups of the polyelectrolyte is &gE;1. The polymeric complex is made by a template-guided chemical polymerization process which comprises adsorbing the monomers onto the polyelectrolyte in a mixture of alcohol and water to form a polyectrolyte adduct, emulsifying the polyelectrolyte adduct in an acid to form an emulsified polyelectrolyte adduct and oxidatively polymerizing the emulsified polyectrolyte adduct. The polymeric complex is water insoluble when dried as a coating on a substrate.

Conducting polymers for coatings and antielectrostatic applications

The template-guided synthesis of water-soluble, chiral conducting polymer complexes is described. Synthesis of water-soluble polyaniline complexes is achieved by carefully controlling the experimental parameters such as; acid concentration, ionic strength, monomer/template ratio, total reagent concentration, and order of reagent addition. Chiral (helical) polyaniline complexes can be synthesized by addition of a chiral inducing agent (chiral acid) prior to polymerization, and the polyaniline helix can be controlled by the addition of the (&plus;) or (&minus;) form of the chiral acid. Moreover the quantity of chiral acid and the salt content has a significant impact on the degree of chirality in the final polymer complexes. The polyaniline and the template have been found to be mixed at the molecular level which results in chiral complexes that are robust through repeated doping and dedoping cycles.

Chemical synthesis of water-soluble, chiral conducting-polymer complexes

A molecular complex which comprises a biopolymer having a plurality of ionic functional groups and a conductive polymer having charges therein. The charges bind to the ionic functional groups to form the complex. The conductive polymer is selected from the group consisting essentially of polyaniline, polypyrrole, polythiophene, poly(phenylenevinylene) or poly(phenylene sulfide) and substituted versions thereof.

Water soluble polymeric complex comprising a conducting polymer and a biopolymer

An anti-corrosive polymeric complex which is comprised of a plurality of double-stranded molecular complexes. Each of the molecular complexes are comprised of a strand of a conductive polymer and a strand of a copolymer. The strands of the polymeric complex are non-covalently bonded to each other along the contour of the strands to form a side-by-side, twisted, double-stranded configuration.

Electroactive polymer coatings for corrosion control

A processable, electrically conductive polymer composition comprises a molecular complex made by template guided chemical polymerization and having a polyelectrolyte and a conductive polymer. A process of preparing a processable, electrically conductive polymer composition comprises the steps of oxidative polymerizing the monomers (abbreviated as AN) for a conductive polymer in the presence of a polyelectrolyte which serves first as a template (abbreviated as TEMP) that binds AN to form a template-(AN)n complex; and adding an oxidant to the template-(AN)n complex for conducting an oxidative polymerization to obtain a molecular complex of a polyelectrolyte and a conductive polymer.

Electrochromic material, i.e. polyaniline, is polymerized in situ in a polymeric electrolyte to form an electrochromic/polyelectrolyte mixture. The mixture is coated as a film on electrochromic material. A film of electrolyte is placed in ion transfer relationship with the electrochromic/polyelectrolyte film. This electrochromic/polyaniline/polyelectrolyte film greatly increases the ion transfer between the electrochromic film and the electrolytic film by imposing a region of molecularly mixed electrochromic material and electrolyte.

A method of forming a thin film of an electrochromic material is disclosed. The method involves coating an acidic solution containing monomeric aniline and effective amounts of an oxidant and a catalyst on the surface on which the electrochromic film is to be formed. The monomeric aniline polymerizes in situ on the surface to from the electrochromic film.
