An electrically conductive bonding tape includes a conductive self-supporting first layer conductive in each of three mutually orthogonal directions and including conductive opposing first and second major surfaces, an conductive second layer coated on the first major surface of the self-supporting first layer and having at least 60% by weight of nickel, the second layer having an exposed major surface facing away from the first major surface of the self-supporting first layer and exposing at least some of the nickel in the second layer, and a conductive adhesive third layer bonded to the second major surface of the self-supporting first layer opposite the second layer. The adhesive third layer is conductive in at least one of the three mutually orthogonal directions and includes a plurality of conductive elements dispersed in an insulative material, at least some of the conductive elements physically contacting the self-supporting first layer.

Electrically conductive bonding tape with low passive intermodulation

A dihaloorganosilane is represented by the formula (I): Each X independently represents Cl, Br, or I. Each Arindependently represents a phenylene group optionally substituted by 1 to 4 alkyl groups selected from methyl or ethyl. Each Rindependently represents an alkylene group having from 2 to 18 carbon atoms. Each Rindependently represents methyl or ethyl. Each Rindependently represents an alkylene group having from 1 to 18 carbon atoms. Each Rindependently represents an alkylene group having from 2 to 18 carbon atoms, and n is an integer in a range of 0 to 5, inclusive. Ionic organosilanes preparable from the dihaloorganosilanes are represented by the formula (II): Membrane compositions and membranes containing the ionic organosilanes are also disclosed.

Cationic copolymers having pendant N-allylimidazolium-containing groups are provided. The cationic copolymers can be used, for example, to provide anion exchange membranes for use in electrochemical cells such as fuel cells, electrolyzers, batteries, and electrodialysis cells. The anion exchange membranes typically have good mechanical properties and ionic conductivity.

Cationic copolymers with pendant N-allylimidazolium groups

A crosslinkable copolymer is provided. The crosslinkable copolymer has pendant cationic nitrogen-containing groups with some, but not all, of these pendant groups further including a (meth)acryloyl group. The (meth)acryloyl groups can react to form a crosslinked copolymer that is ionically conductive. The crosslinked copolymer can be used to provide an anion exchange membrane that can be used in electrochemical cells such as fuel cells, electrolyzers, batteries, and electrodialysis cells.

Copolymers with cationic, nitrogen-containing groups and anion exchange membranes made therefrom

Cationic polymers are provided that comprise monomeric units of Formula (V). (V) Each asterisk (*) indicates an attachment position to another monomeric unit; R is hydrogen or methyl; each Ris each independently an alkyl, aryl, or a combination thereof; L is a linking group comprising an alkylene group; and +Ris a cationic nitrogen-containing group free of any N&#x2014;H bonds. Membranes formed from said cationic polymers, devices including such membranes, and methods of making such cationic polymers are also provided.

Copolymers containing pendant ionomeric carbosilane groups

Described herein are cationic polymers having a plurality of quaternary amino groups, methods of making such polymers, and uses of such polymers as ion exchange membranes in electrochemical devices.

Hydrocarbon polymers containing ammonium functionality

Described herein is a process for the reduction of carbon dioxide comprising:

Ionic polymer membrane for a carbon dioxide electrolyzer

Cationic polymers for use as anion exchange polyelectrolytes

Described herein is a process for the reduction of carbon dioxide comprising: providing an electrochemical device comprising an anode, a cathode, and a polymeric anion exchange membrane therebetween, wherein the polymeric anion exchange membrane comprises an anion exchange polymer, wherein the anion exchange polymer comprises at least one positively charged group selected from a guanidinium, a guanidinium derivative, an N-alkyl conjugated heterocyclic cation, or combinations thereof; introducing a composition comprising carbon dioxide to the cathode; and applying electrical energy to the electrochemical device to effect electrochemical reduction of the carbon dioxide.
