Title: Porous metals from sintering of nanoparticles

Abstract

A method including encapsulating or capping metallic nanoparticles by a dendrimer or a polymer with binding sites for metal particless or metal ions dispersed in a fluid; modifying the fluid to disrupt the interaction of the dendrimer or polymer with the particles; and subsequently or concomitantly sintering or partially consolidating the zero valent metal. A method including introducing a first metal salt and a second metal salt into a dendrimer or a polymer with binding sites for metals or metal ions; reducing a metal ion of the first metal salt to a zero valent first metal and a metal ion of the second metal salt to a zero valend second metal; disrupting an interaction between the dendrimer or the polymer and the first metal and the second metal; and sintering or partially consolidating the first metal and the second metal.
