Problems solved by technology

Since each carbon nanotube is a closed structure, the carbon nanotubes in the above-mentioned carbon nanotube film are connected end-to-end by van der Waals force in the direction of carbon nanotube arrangement, so that there are a large number of connections between carbon nanotubes in the carbon nanotube film. Points, these connection points only exist van der Waals force, which weakens the performance of the carbon nanotube film and limits its application range

Abstract

The invention relates to a nanotube film comprising a plurality of nanotubes. The plurality of nanotubes are arranged in an orderly manner and connected to each other to form a self-supporting structure, and part of the junctions of two adjacent nanotubes are bonded by ionic bonds.

Description

technical field [0001] The invention relates to a nanotube film, in particular to a nanotube film composed of nanotubes. Background technique [0002] Nanomaterials are of great value in basic research and practical applications, such as catalysis and sensing. Therefore, the preparation of nanomaterials with macrostructure has become a research hotspot. [0003] Currently, methods for preparing nanomaterials include spontaneous growth, template-based synthesis, and lithography. However, the nanomaterials prepared by the above methods are usually in powder form and cannot form a self-supporting structure, that is, the nanomaterials need a supporting structure to maintain a specific shape, such as a wire or a film. Therefore, the application range of nanomaterials is limited. [0004] The prior art provides a method for preparing a carbon nanotube film structure, please refer to the application of Fan Shoushan et al. on February 9, 2007, and the No. CN101239712B Chinese Ann...
