Problems solved by technology

In the sol-gel method, because the sol contains a large amount of water, the film is easy to crack during heat treatment; in the spray pyrolysis method, a large amount of harmful impurities in the precursor are difficult to remove because the film is formed directly on the surface, while the alkoxide hydrolysis method needs to consume a large amount of organic matter. Alcohol, higher cost

Embodiment 1

[0025] Embodiment 1: Preparation of antimony-doped tin oxide powder

[0026] Prepare 50ml of 2mol / L HCl solution, mix 152g of SnCl 4 ·5H 2 O and 22 g of SbCl 3 Dissolve in HCl. Prepare 5mol / L NH 3 ·H 2 O solution, gradually add the acid solution and lye solution into 1400ml of distilled water with a constant temperature of 58°C and continuous stirring, and add SnCl drop by drop method. 4 and SbCl 3 solution. After the reactant was added dropwise (according to the drop of the acid solution), the mother liquor was stirred for 1 hour, so that the reaction was complete. After the reaction was over, the stirring was stopped and left to stand for 1 hour.

Abstract

The invention relates to a preparation method of a transparent conductive material containing antimony-doped tin oxide (ATO), comprising: preparing ATO powder modified by a surface modifier and a coupling agent, and dispersing it into water to form an ATO water slurry ; Prepare polymer copolymer emulsion; Disperse the modified ATO water slurry into the polymer emulsion, and add a certain amount of pH regulator to change the pH value of the system, thereby obtaining a stable and highly dispersed ATO aqueous dispersion; The polymer emulsion particles are used as a binder, so that the transparent conductive material formed after the aqueous dispersion is dried has good electrical conductivity and optical transparency when the content of conductive filler is low. Transient, can be widely used in various antistatic, anti-radiation coating materials and various transparent conductive profiles.

Description

technical field [0001] The invention relates to a preparation method of a conductive material, in particular to a preparation method of a transparent conductive material containing antimony-doped tin oxide. Background technique [0002] With the development of information technology, various optoelectronic products are changing with each passing day, which puts forward higher requirements for the performance of transparent conductive materials. Transparent conductive materials combine the characteristics of transparency and conductivity, and have a wide range of applications. They can not only be used in anti-static, anti-glare, and anti-electromagnetic radiation of picture tubes or display screens, but also in transparent electrodes, solar photoelectric conversion, and other fields. [0003] At present, most conductive materials are opaque, and the only known materials that are transparent and conductive at the same time are indium tin oxide (ITO) and antimony-doped tin oxi...
