The present invention is directed to a process for making silver nanostructures, comprising reacting at least one polyol and at least one silver compound that is capable of producing silver metal when reduced, in the presence of a source of chloride or bromide ions, at least one copolymer, and at least one acid scavenger. The present invention is also directed to silver nanostructures made by the processes described herein.

Processes for making silver nanostructures

A polymer film, polymer gel, and polymer foam each contain an electrically conductive polymer and an ionic liquid and are each useful as a component of an electronic device.

Polymer compositions, polymer films, polymer gels, polymer foams, and electronic devices containing such films, gels and foams

A process for making silver nanostructures, which includes the step of reacting at least one polyol and at least one silver compound that is capable of producing silver metal when reduced, in the presence of: (a) a source of chloride or bromide ions, and (b) at least one copolymer that comprises: (i) one or more first constitutional repeating units that each independently comprise at least one pendant saturated or unsaturated, five-, six-, or seven-membered, acylamino- or diacylamino-containing heterocylic ring moiety per constitutional repeating unit, and (ii) one or more second constitutional repeating units, each of which independently differs from the one or more first nonionic constitutional repeating units, and has a molecular weight of greater than or equal to about 500 grams per mole, is described herein.

Process for making silver nanostructures and copolymer useful in such process

Disclosed are methods and systems for transferring dry or semi-dry nanoparticles onto a substrate. In one embodiment, this includes the steps of providing a roller comprising an elastomeric stamp; transferring nanoparticles in a dry or semi-dry state, and which contact the surface of a donor substrate, from the donor substrate onto the elastomeric stamp; and depositing the dry or semi-dry nanoparticles from the elastomeric stamp onto a receiver substrate by rolling the elastomeric stamp onto the receiver substrate. The substrate, in other embodiments, can have a relief structure.
