Preparation and Use of Silver Alloy Composite Nanomaterial

Abstract

The present disclosure provides a method of preparing a silver alloy composite nanomaterial. The preparation method comprises forming a silver alloy comprising at least one of copper, zinc, magnesium, aluminum and titanium into a composite metal rod; evaporating the silver alloy of the composite metal rod, resulting in a gaseous alloy; rapidly cooling the gaseous alloy so as to condense the silver alloy into a solid state; and collecting the cooled powder so as to obtain the silver alloy composite nanomaterial.
