Abstract

The invention discloses a method and a device for the mass production of nanowires. The method comprises the following steps: preparing a nano-porous substrate, and forming a plurality of parallel through holes in the surface of the nano-porous substrate; One or more kinds of metal powder are provided, the particle size of the metal powder is smaller than 100 m, and the metal powder is evenly laidon the nano-porous substrate; The preparation method comprises the following steps: preparing a nano-porous substrate into a cavity, and establishing a high-vacuum environment in the cavity; Heatingthe interior of the cavity to melt the metal powder into a molten metal; And the holes poured into the nano-porous substrate are die-cast into a plurality of nano-wires by the molten metal in the pressurizing cavity.

Description

technical field [0001] The present invention relates to a manufacturing method of a wire and a manufacturing device thereof, in particular to a mass production manufacturing method of a nano wire and a manufacturing device thereof. Background technique [0002] Due to the increasingly serious environmental pollution and industrial demands, the development of sensors has been paid much attention. Today, when the air pollution control is becoming more and more complex and the industry is in urgent need, more and more attention is paid to high-efficiency gas sensors. [0003] In recent years, with the emergence of gas sensors of nanostructured materials, their sensitivity can increase significantly with the reduction of the size of the agglomerates. Nanoparticle materials smaller than 100 nanometers have a small particle size and a large surface area for reaction, so they must have As far as the gas sensor with good surface effect is concerned, it has considerable application ...
