Abstract

The invention discloses a method for rapidly preparing copper nanowires at low cost. The method comprises the following steps: (1) firstly, mixing two kinds of divalent copper salt powders of copper nitrate and copper chloride, adding a long-chain macromolecule organic amine hexadecane, adding reducing sugar and deionized water, and obtaining a mixed liquid A; (2) placing the mixed liquid A at room temperature, stirring for 9-11 h, heating for 5-6 h after stirring, and obtaining a mixed liquid B; (3) centrifuging the mixed liquid B, and centrifuging and washing precipitates at the bottom withdeionized water of 60 to 90 DEG C at 6000 r/min to 9000 r/min. The method is easy and fast to operate, and can be used to prepare the copper nanowires with an excellent length-diameter ratio, the costis reduced by 9% to 20% compared to the prior art, and the reaction rate is increased by 10% to 15%.

Description

technical field [0001] The invention relates to the field of metal nanowires, in particular to a method for rapidly preparing copper nanowires at low cost. Background technique [0002] In the field of modern nanoscience and technology, copper nanowires have become excellent materials for preparing transparent and flexible conductive electrodes due to their unique optical, electrical, mechanical and thermal properties. Copper is cheap, the conductivity of copper is only 6% lower than that of silver, and its reserves are 1000 times richer than silver, the price is only about 1% of silver or ITO, the natural storage capacity is large, and it is an ideal material to replace precious metals in practical applications , it is possible to replace ITO and silver nanowires. [0003] How to prepare monodisperse and stable copper nanowires has also become a research hotspot in this field. Among various methods for preparing copper nanowires, the liquid phase reduction method can not ...
