Abstract
Metal nanowires, such as silver nanowires coated on a substrate were fused together to form fused metal nanowire networks that have greatly improved conductivity while maintaining good transparency. Materials formed form the fused metal nanowire networks described herein can have a transparency to visible light of at least about 85% and a sheet resistance of no more than about 100 Ohms/square or a transparency to visible light of at least about 90% and a sheet resistance of no more than about 250 Ohms/square. The method of forming such a fused metal nanowire networks are disclosed that involves exposure of metal nanowires to various fusing agents on a short timescale. When formed into a film, materials comprising the metal nanowire network demonstrate low sheet resistance while maintaining desirably high levels of optical transparency, making them suitable for transparent electrode formation.
