Abstract

The invention discloses a quintuple twin-crystal seed induced silver nanowire and a preparation method thereof. The quintuple twin-crystal seed induced silver nanowire and the preparation method thereof overcome the problems of high impurity and low uniformity of an existing polyhydric alcohol reduction method. The method comprises the steps of smelting gold salt and silver salt in a reductive solvent to form cores so as to obtain twin-crystal seed crystals which are characterized in that the twin-crystal boundary is not ended in geometrical boundary; and then adding a halogens catalyst and silver salt to react under high temperature so as to obtain high-yield single-dispersity silver nanowire of which the surface is provided with a protruded surface or sunken surface substructure; and theside surface of the silver nanowire is incompletely-exposed {100} crystal surface. According to the preparation method, the quintuple twin crystals are quickly smelted to form core so as to obtain the uniform seed crystals; and the synthesized silver wire is high in single dispersity and high in controllability.

Description

technical field

[0001] The invention belongs to the technical field of metal functional materials and nanomaterials, and in particular relates to a silver nanowire induced by five-twin seeds and a preparation method thereof. Background technique

[0002] Silver nanowires have attracted widespread attention due to their small size, large specific surface area, good catalytic properties, antibacterial properties, and biocompatibility. In addition, due to its excellent conductivity, ductility and stretchability, silver nanowires can be made into transparent conductive films, replacing ITO, and are widely used in flexible touch displays and large-size touch displays.

[0003] At present, there are many reports on the research of silver nanowires, see "Large scale preparation of silver nanowires with different diameters by a one-pot method and their application in transparent conducting films", RSC Adv.8096, 6, 2016; "Hydrothermal synthesis method Preparation of silver nanowires...
