Abstract

Branched nanowire preparation methods, compositions, and articles are disclosed. Such branched nanowires are useful for electronics and optical applications.

Claims

exact text as granted — not AI-modified
What is claimed: 
     
         1 . A method comprising:
 providing at least one first silver metal ion; and   reducing the at least one first silver metal ion to at least one first branched silver metal nanowire in the presence of at least one of a second metal ion comprising at least one of an ion of an IUPAC Group 5 element, an one ion of an IUPAC Group 6 element, or a ruthenium ion,   wherein the branched silver metal nanowire consists of elemental silver.   
     
     
         2 . The method according to  claim 1 , wherein the at least one second metal ion comprises at least one of a vanadium ion, a tungsten ion, or a ruthenium ion. 
     
     
         3 . The method according to  claim 1 , wherein the reduction occurs in the presence of at least one of a protecting agent or a polyol. 
     
     
         4 . The method according to  claim 1 , wherein the branched silver metal nanowire comprises two or more branch points.
