Abstract

The invention belongs to the technical field of novel functional nanometer material preparation method and discloses a nanometer wire purifying device and a purifying method. The invention comprises the following steps: adding a liquid medium into a first container; adding a nanometer wire to be purified under stirring, wherein the nanometer wire to be purified is a mixture of nanometer wires and nanometer particles; uniformly mixing to form a suspending liquid and injecting the suspending liquid into a tubular filter by a transfer pump; adjusting pressure differences between inlet and outlet ends of the tubular filter to make part of the liquid to leak from a side wall of the tubular filter and rest of the liquid to leak from the outlet of the tubular filter; collecting the liquid leaking from the side wall and the outlet of the tubular filter by a second container and a third container respectively; and filtering the liquid collected in the third container to obtain solids to obtain the purified nanometer wire. According to the invention, mesh diameter of the tubular filter is bigger than particle diameters of the nanometer particles but smaller than length of the nanometer wire. The purifying device and the purifying method of the invention are characterized by simple device, simple process, low cost, high product yield and the like. The purifying device and the purifying method of the invention can be used to obtain nanometer wires of high purity.

Description

technical field [0001] The invention belongs to the technical field of preparation of novel functional nanometer materials, and in particular relates to a nanowire purification device and a purification method. Background technique [0002] As a one-dimensional nanomaterial, nanowires have completely different properties from zero-dimensional nanoparticles, and have a wide range of applications in solar cells, electronic materials, conductive materials, catalytic materials, polymer composite materials, and other fields. In recent years, the preparation methods of nanowires have attracted great attention of researchers. The preparation methods reported at present are mainly divided into template method and seed method. The template method is limited by the template and the template needs to be removed after the preparation is completed. Suitable for large-scale industrial preparation. The principle of preparing nanowires by the seed method is that the nanowires grow epitaxia...
