Abstract

The invention discloses a uniform and transparent conductive film with long-tube-bundle carbon nanotubes and a preparation method of the uniform and transparent conductive film, and belongs to the technical field of transparent conductive films. The method comprises the following steps: by adopting a floating catalytic chemical vapor deposition method, taking ethanol, toluene and acetonitrile as carbon sources, taking a sulfur-containing compound as a growth promoter and taking ferrocene, nickelocene and cobaltocene as catalysts, injecting a mixed solution of the carbon sources, the growth promoter and the catalysts into a high-temperature tubular furnace at a certain speed under the action of inert gas and hydrogen by utilizing a sample injection system, and performing high-temperature sintering to obtain the high-performance carbon-based composite material. And collecting the carbon nanotubes grown in the gas phase to a filter membrane to obtain the uniform and transparent conductive film with the long-tube-bundle carbon nanotubes. The carbon nanotube prepared by the method is long, and the number of contact junctions in the film is effectively reduced, so that the conductivity of the carbon nanotube film is remarkably improved.

Description

Technical field [0001] The present invention belongs to the technical field of transparent conductive film, and in particular, the present invention relates to a conductive film having a long tube bundle carbon nanotube and a uniform and transparent method. Background technique [0002] Carbon nanotube transparent conductive films have a wide range of applications in modern electronics, including photovoltaic, touch screens, liquid crystal displays, organic light emitting diodes and other fields. Carbon nanotubes transparent conductive film is expected to replace the potential of conventional indium tin oxide films. The method of preparing carbon nanotube transparent conductive film today is mainly divided into dry and wet preparation. Among them, the wet method preparing carbon nanotube film is usually dispersed in a surfactant, and then the film is formed into a film (H.-Z.geng, K.K.Kim, K.p. So, Y.S.H via ultrasound, centrifugal, and filtration. Lee, y.chang and y.s.h.lee, J.A...
