摘要:
Electrochemical cells, and more specifically, release systems for the fabrication of electrochemical cells are described. The release layers described herein may be conductive release layers. In particular, conductive release layer arrangements, assemblies, methods and compositions that facilitate the fabrication of electrochemical cell components, such as electrodes, are presented. In some embodiments, methods of fabricating an electrode involve the use of a release layer to separate portions of the electrode from a carrier substrate on which the electrode was fabricated. For example, an intermediate electrode assembly may include, in sequence, an electroactive layer, an optional current collector layer, a conductive release layer, and a carrier substrate.

Polyvinyl alcohol (PVOH) and polyphenyl sulfone (PPSU) organo-silanes that are stable in high temperature, high UV and/or high humidity environments are described. The PVOH and PPSU organo-silanes are useful for a variety of uses, such as anti-corrosion coatings, barrier coatings, high temperature paints, pharmaceutical coatings, pipe coatings, and tank liners. Additionally, methods for the preparation of the PVOH and PPSU organo-silanes are described herein.
摘要:
A method for coating a substrate includes impacting a substrate with a plurality of particles such that the particles adhere to the substrate, bonding the particles to the substrate to form an overlayer, and crosslinking the particles in the overlayer to coat the substrate with a crosslinked polymer coating. The particles comprise a polyphenyl polymer. An article includes a substrate and a crosslinked polymer coating bonded to the substrate. The crosslinked polymer coating is a product of crosslinking polyphenylene sulfide, polyphenylsulfone, self-reinforced polyphenylene, or a combination thereof on a surface of the substrate.

摘要:
The present invention provides an aqueous coating composition comprising (i) particles of a non-melt processible polymer of tetrafluoroethylene and (ii) a non-fluorinated polymer selected from the group consisting of a polysulfone, a polyamide, a polyimide, a polyamide-imide, a polybismaleimide and mixtures thereof, wherein said particles are core-shell particles whereby the shell comprises a copolymer of tetrafluoroethylene and a partially fluorinated or non-fluorinated comonomer. The aqueous coating composition may be used for providing a primer coating on a substrate such as a metal or glass substrate. Such primer coating may provide good or excellent non-stick coatings combined with good or excellent scratch and wear resistance of the coating. Also, such primer coating may provide for good to excellent PTFE coatings that can resist hot salt water. The aqueous coating composition may also be used to provide other coating layers of a multi-layer coating.
摘要:
Powders of oxidized polyarylene sulfide and powders comprising from 1 to 99% by weight of oxidized polyarylene sulfide and from 1 to 99% by weight of a metal, carbide, ceramic or high temperature polyimide, polyamide imide, polyester imide and aromatic polyester plastic, or a mixture thereof are very suitable for use in thermal spraying and thereby form coatings having a strong chemical and mechanical resistance and high dimensional stability when exposed to high and low temperatures. Such coatings are advantageous for use as abradable seal clearance control coating in the compressor section of gas turbine engines, motor vehicle turbochargers and superchargers, and for use as a coating of reaction vessels, kitchen ware, sealings or bearings.
