摘要:
A non-aqueous photocurable composition contains dispersed carbon-coated metal particles in an organic diluent in an amount of at least 10 weight %. The dispersed carbon-coated metal particles have a median diameter equal to or less than 0.6 μm, and are dispersed using a particle dispersing agent that has a weight average molecular weight (Mw) of at least 2,000 and up to and including 100,000 and comprises nitrogen-containing units. The median diameter of the dispersed particles is determined using a dynamic light scattering method. Moreover, when the non-aqueous composition contains up to and including 25 weight % of the dispersed carbon-coated metal particles, it exhibits no visual settling when subjected to a settling test of at least 24 hours at 20° C. Such non-aqueous photocurable compositions include photocurable components and are useful to prepare photocurable and photocured electrically-conductive patterns and layers in various articles, including touch screen devices having touch screen displays.

Electroless copper plating baths include alternative reducing agents to the conventional reducing agents currently used in the electroless plating industry. The electroless copper baths are stable and deposit a salmon bright copper deposit on substrates. Exclusion of many environmentally unfriendly conventional reducing agents enables environmentally friendly electroless copper plating baths.

A method for fabricating printed electronics includes printing a trace of an electrical component on a first substrate to form a first layer. The method further includes printing a trace of an electrical component on at least one additional substrate to form at least one additional layer. The first layer is stacked with the at least one additional layer to create an assembled electrical device. At least one of the layers is modified after printing.

A defect-free hydrogen separation membrane includes a metal thin membrane. The metal thin membrane includes a first metal layer composed of palladium on a porous support without substantial penetration into surface pores of the porous support and a second metal layer on the first metal layer. The second metal layer is a product of palladium deposition and closes defects being open on the surface of the first metal layer.

The present invention concerns an electroless nickel plating bath suitable for application in plating on plastic processes. The plating bath is free of hazardous substances such as lead ions and ammonia and allows deposition of nickel phosphorous alloys on plastic substrates at plating temperatures not higher than 55° C. Furthermore, the deposition of copper from an immersion type copper plating bath onto the nickel phosphorous coatings require no activation step which results in less process steps and less waste water production.
