Abstract

The invention discloses a polliwog-shaped metal copper nanomaterial and a preparation method thereof, which fill the blank of the prior art at home and abroad and add a novel variety for a metal copper nanostructure material. The appearance of the metal copper nanostructure is polliwog-shaped; the structure is uniform and is mono-dispersed; the length of the polliwog-shaped material is about 4-5 micrometers; the head part of the polliwog-shaped material consists of hexagonal nanosheets of which the sizes are 600-800 nanometers; the body of the polliwog-shaped material consists of nanowires ofwhich the diameters gradually decrease from the head part; the nanowires have high flexibility; and the tail part is crimped. The polliwog-shaped metal copper nanomaterial is prepared by adopting a microwave-assisted liquid phase reduction method in which a soluble copper salt, hexamethylene tetramine and ascorbic acid are taken as raw materials, water is taken as a solvent and a reaction mixed liquor undergoes a microwave radiation reduction reaction in a household microwave oven. The polliwog-shaped metal copper nanomaterial obtained with the method has a novel structure. The preparation method has the advantages of simple preparation process and equipment, readily available raw materials, low cost, mild reaction condition, no use of surfactant or organic solvent, low carbon, environmental friendliness, high repeatability and suitability for industrial production.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a "tadpole" metallic copper nanomaterial and a preparation method thereof. Background technique [0002] Nanotechnology is a high-tech emerging at the end of the 20th century, and occupies an important position in the field of material science. Nano-copper powder is brownish-red, due to the characteristics of small size, large specific surface area, large number of surface active centers, small resistance, quantum size effect, macroscopic quantum tunneling effect, etc., it shows new characteristics different from conventional pure copper, and has excellent Catalytic, lubricating, electrical conductivity, has been widely developed and applied. For example, it is used as a catalyst to catalyze the synthesis of important chemical industrial products (such as acetylene polymerization); it is used as a new type of wear-repairing lubricating additive for gasoline engi...
