This invention relates to a process of forming a polymeric nanocomposite comprising a continuous polymeric phase formed from a melt processible polymer having amelt processing temperature equal to or greater than about 220.degree. C. and platelet particles having an average thickness equal to or less than about 50 .ANG. and a maximum thickness of about 100 .ANG. having a secondary or primary ammonium cationic complex, a quaternary phosphonium cationic complex bonded to surface of said particles, the composite material formed by said process and an article formed from the composite material.

Melt process formation of polymer nanocomposite of exfoliated layered

This invention is directed to a composite formed from a gamma phase polyamide such as nylon 6 having dispersed therein a particulate material such as a phyllosilicate as for example montmorillonite.

Nanocomposites of gamma phase polymers containing inorganic particulate

The invention provides a method for forming deposits of superconducting ceramics by sequentially electrodepositing layers of metals, of a type and in proportion suitable for forming a superconducting ceramic, to form a precursor metal deposit, followed by oxidizing the precursor deposit to form a superconducting ceramic deposit. Optionally, the electroplating steps are conducted in such a manner that a patterned precursor deposit results, to obtain a patterned superconducting deposit after oxidation.

Superconducting ceramics by sequential electrodeposition of metals,

Superconducting ceramic layers are made by first electrochemically depositing metal layers containing embedded particulate matter, followed by oxidation of the precursor layer to form the desired superconducting ceramic. The embedded particulate matter may (a) furnish required constituent metals for the superconductor, (b) be a superconductor itself, which may be the same as or different from the superconductor to be formed, or (c) provide adjuvant substances for improving the properties (e.g., electrical or mechanical) of the superconducting layer being formed.

Superconducting ceramics by electrodeposition of metals with embedment

The invention relates to an improvement in a method of forming deposits of superconducting ceramics. Generally, such ceramics are formed by electrodepositing a mixture of metals of the type and in proportions sufficient to be oxidized into ceramic; oxidizing the electrodeposited mixture under conditions sufficient to result in a superconducting ceramic deposit; and orienting the crystallites in said superconducting ceramic deposit. Crystallite orientation may take place before, after or during the oxidation step.

Method of forming crystallite-oriented superconducting ceramics by

A method of fabricating an electrode which comprises an intimate mixture of finely divided electroactive material in a matrix composed of a conjugated backbone polymer which comprises the steps of: derivatizing the surface of finely divided alkali-metal alloying metal, alkali metal cation inserting material or anion inserting material with active polymer catalyst; dispersing the derivatized metal or material having a desired small particle size in a gas, suspension or solution of a monomer or other precursor of the desired conjugated backbone polymer and polymerizing the monomer and/or precursor in the presence of the dispersed metal or material; and fabricating a cohesive solid by recovering the polymerization product from said gas, suspension or solution comprising derivatized metal or material coated with conjugated backbone polymer and forming same into a cohesive solid.

Process for forming articles of filled intrinsically conductive polymers

The invention relates to an improvement in a method of forming deposits of superconducting ceramics. Generally, such ceramics are formed by electrodepositing a mixture of metals of the type, and in proportions sufficient to be oxidized into ceramic, onto a substrate. The electrodeposited mixture is then oxidized under conditions sufficient to result in a super conducting ceramic deposit. The improvement resides in conducting the electrodeposition in a manner which results in a patterned electrodeposition prior to conducting oxidation.

Method of forming superconducting ceramics by electrodeposition

A method of forming films of superconducting ceramics is disclosed. The method involves electrodepositing a mixture of metals of the type which can be oxidized into superconducting ceramic. Thereafter, the metals deposited are oxidized to form the superconducting ceramic deposit. Deposits made by this method are also disclosed.

This invention relates to a novel anode for use in batteries, and to batteries containing the anode, which anode comprises one or more anode active materials and an elastomeric binder.

Elastomeric binders for battery electrodes

This invention relates to a novel anode for use in batteries, and to batteries containing the anode, which anode comprises a mixture of a conjugated backbone polymer and another electroactive material selected from the group consisting of metals which alloy with alkali metals and alkali metal cation inserting materials as for example transition metal chalcogenides.

Negative electrodes for non-aqueous secondary batteries composed on

Batteries wherein at least one of the anode and cathode is a conjugated backbone polymer and in which the electrolyte contains at least one sultone or sulfonate solvent. Preferred solvents such as propane sultone and butane sultone impart stability to the battery and permit the polymer, such as polyacetylene, to be highly oxidized or reduced without degradation.

Conjugated polymer battery containing organosulfur solvent

Rechargable battery with a conjugated backbone polymer anode which has been coated, when in the reduced state, by contact with a monomer with a reactive oxirane group. Reduced polyacetylene anodes, after reaction with ethylene oxide, offer improved stability to solvents.

Battery having polymeric anode coated with reaction product of oxirane

Batteries are disclosed with electrodes, especially cathodes, having a conjugated backbone polymer such as polyacetylene as electroactive material and a coating. The coating is formed by reaction between the oxidized polymer and a pyrrole, thiophene, azulene, furan or aniline compound.

Polymeric electrode coated with reaction product of cyclic compound

Conjugated backbone polymer electrodes such as polyacetylene anodes are coated with the reaction product of the reduced polymer with a sultone or sulfonate. Such coating may have occurred by using a sultone such as propane sultone in the electrolyte of a battery with such an anode, or in electrode preparation. The coating improves the stability of the electrode, especially when the polymer is highly reduced during battery use, whether the sultone remains as all or part of the electrolyte, or the sultone is replaced by a solvent such as propylene carbonate in the electrolyte for the battery containing coated electrode.
