Electrostatic Field Force Directed Gold Nanowires from Anion Exchange Resin

Abstract

We have developed a polarization-induced growth process to synthesize gram quantity of gold nanowire (Au NW) on the outer surface of an anion exchange resin matrix. This new, simple, modified hydrothermolysis (MHT) procedure involving resin-bound HAuCl4 produced micrometer long Au nanowire on resin surface. The charged resin matrix responsibly imposes electrostatic field effect (EFF) for 1D growth of Au NWs in the presence of different amines or derivatives of amines. The Au nanowire is separated from resin by sonication. Again, the synthesis of MnO2 nanowire with resin support through similar MHT strengthens the 1D growth proposition, that is, EFF-induced polarization effect.
