Abstract
A low temperature sinterable copper nanoparticle or nanowire, comprising gold, zinc, nickel, tin, or aluminum as an alloying metal, and a capping agent. The nanoparticles or nanowires may be deposited on porous or fibrous substrates, the capping agent desorbed, and sintered at low temperature to form conductive traces or sensing elements. The nanoparticles or nanowires may be deposited by aerosol jet, inkjet or dispenser printers, for example.
