Problems solved by technology

[0004] However, in the carbon nanotube film obtained by the preparation method of the above-mentioned carbon nanotube film, the distribution of carbon nanotubes is uneven, and a plurality of carbon nanotubes are intertwined to form large-diameter carbon nanotube bundles. In applications, due to these large-diameter The presence of carbon nanotube bundles, the light transmittance of the general carbon nanotube film is less than 75%

preparation example Construction

[0016] see figure 1 , the embodiment of the present invention provides a method for preparing a transparent carbon nanotube film, which includes the following steps:

[0017] Step 1: providing a carbon nanotube film.

[0018] The carbon nanotube film is composed of a plurality of carbon nanotubes. A plurality of carbon nanotubes in the carbon nanotube film are combined with each other by van der Waals force, and are arranged substantially parallel to the surface of the carbon nanotube film. Further, the carbon nanotubes in the carbon nanotube film can be arranged in an orderly or disorderly manner. The so-called order means that the carbon nanotubes in the carbon nanotube film have certain rules in the arrangement direction; the so-called disorder means that the carbon nanotubes in the carbon nanotube film have certain rules. The arrangement of carbon nanotubes in the film is regular, isotropic, and intertwined. Preferably, the carbon nanotube film has a certain self-suppor...

Abstract

The invention relates to a transparent carbon nanotube membrane preparing method, comprising following steps: providing a carbon nanotube membrane composed of a plurality of surfaces of the carbon nanotubes fundamentally in parallel with the carbon nanotube membrane; and heating the carbon nanotube membrane, wherein parts of the carbon nanotubes in the carbon nanotube membrane are oxidated, thus the carbon nanotube membrane is thinning. The prepared transparent carbon nanotube membrane is applicable to the field of the transparent electrode, the thin-film transistor and the touch screen.

Description

technical field [0001] The invention relates to a preparation method of a carbon nanotube film, in particular to a preparation method of a transparent carbon nanotube film. Background technique [0002] Since the first discovery of carbon nanotubes (Carbon Nanotube, CNT), nanomaterials represented by carbon nanotubes have attracted great attention due to their unique structures and properties. In recent years, with the continuous deepening of research on carbon nanotubes and nanomaterials, their broad application prospects continue to emerge ("Carbon Nanotube-the Route to Applications", Ray H.Baughman, et al.Science297, 787 (2002)) . Due to the unique electromagnetic, optical, mechanical, and chemical properties of carbon nanotubes, a large number of applications in fields such as field emission electron sources, sensors, new optical materials, and soft ferromagnetic materials have been continuously reported. [0003] Carbon nanotube film (Carbon Nanotube Film, CNT Film) i...
