A curable composition comprising a fluorinated amorphous fluoropolymer, and a blend of polysulfonamide and polyol crosslinking agents.

Blends of crosslinking agents for fluoroelastomers

Provided is a curable composition comprising a partially fluorinated fluoropolymer, optionally an organo-onium accelerator an acid acceptor; and a crosslinking component of the formula.

Curable fluoroelastomer composition

An article is provided that includes a substrate, a silicon containing layer on the substrate, and a layer including metallic Pt on the silicon containing layer. The silicon containing layer is a diamond-like glass layer. Optionally, the substrate is a porous membrane. In some cases, the silicon containing layer is a continuous layer.

Fluorinated membrane articles

A water electrolyzer comprises a membrane, a cathode and an anode. The membrane comprises a first membrane layer comprising a first ion-conductive polymer, a second membrane layer comprising a second ion-conductive polymer, and a platinized nanostructured layer disposed between the first layer and the second layer. The platinized nanostructured layer comprises close-packed whiskers having at least one of platinum or platinum oxide disposed thereon. The cathode is disposed on the membrane and comprises a first catalyst consisting essentially of both metallic Pt and Pt oxide. The anode is disposed on the opposite surface of the membrane and comprises a second catalyst comprising at least 95 percent by weight of collectively metallic Ir and Ir oxide, calculated as elemental Ir, based on the total weight of the second catalyst, wherein at least one of metallic Ir or Ir oxide is present. Membranes and methods of making them are also disclosed.

Membrane, membrane electrode assembly, and water electrolyzer including the same

Water electrolyzer comprising a membrane having first and second opposed major surfaces, a thickness extending between the first and second major surfaces, and first, second, and third regions equally spaced across the thickness, wherein the first region is the closest region to the first major surface, wherein the second region is the closest region to the second major surface, wherein the third region is located between the first and second regions, wherein the first and third regions are each essentially free of both metallic Pt and Pt oxide, and wherein the second region comprises at least one of metallic Pt or Pt oxide; a cathode comprising a first catalyst on the first major surface of the membrane; and an anode comprising a second catalyst on the second major surface of the membrane.

Water electrolyzers

Polyester polymers are described comprising polymerized units comprising a hydroxy functional aromatic group wherein the hydroxy group has been functionalized with an adhesion promoting group. In some embodiments, the polyester polymer comprises polymerized units have the general structure (A) wherein Land Lare independently divalent linking groups comprising an ester group; and Ris an adhesion promoting group bonded to the oxygen atom by means of an ionic or covalent bond. In other embodiments, film articles, laminates are described and methods of making functionalized polyester polymers are described.
