Problems solved by technology

The solution method mainly includes spin-coating film-forming method, ink-jet printing method, dipping and pulling method, etc. Although this method has the advantages of simple process and low cost, the film is easy to fall off due to the poor bonding force between the film and the substrate.
Deposition methods mainly include chemical vapor deposition, atomic sputtering deposition and electrochemical deposition. The carbon nanotube film and graphene film prepared by this method have a uniform and dense...

Abstract

The invention relates to a preparation method of a transparent conducting material based on a 3D printing technology. The preparation method is characterized by comprising the following steps of 1) modeling; designing a model of a strip transparent conducting electrode by utilizing computer modeling software, and converting a software command of the model to a mechanical equipment directive of 3D printing so as to control the moving path, the movement speed and the liquid jet velocity of each 3D printing head as well as the moving path, the movement speed and the laser irradiation time of each laser head; and 2) printing the strip transparent conducting electrode. The transparent conducting electrode prepared by the invention has the advantages of good light transmittance and good electrical conductivity and overcomes the defect of poor adhesiveness of between a carbon nano-tube film layer and a substrate and between a graphene film layer and the substrate; and by adopting the method, the thickness and the width of the transparent conducting electrode are precisely controlled.

Description

technical field [0001] The invention relates to a preparation method of a transparent conductive material based on 3D printing technology, which is applied to the preparation of the transparent conductive material. Background technique [0002] The most commonly used transparent conductive electrode materials are indium tin oxide (ITO), fluorine-doped tin oxide (FTO) and aluminum-doped zinc oxide (AZO), these thin film materials have high carrier concentration and low resistivity, And the visible light transmittance reaches 80% ~ 90%, which has been widely used in flat display, building and solar photovoltaic energy system. With the development of optoelectronic devices towards miniaturization, portability, high integration and high sensitivity, ITO, FTO and AZO have large absorption coefficients, high cost, fragility, ion diffusion and rare metal resources in the blue and near-infrared regions. The disadvantage of limitation. Carbon nanotubes and graphene are the most imp...
