Nano silver conductive coating

Abstract

The invention discloses a water-soluble nano silver conductive coating. The raw material formula of the coating consists of the following materials in percentage by mass: 10-30% of nano silver wire dispersing liquid or 3-6% of nano silver wires, 30-50% of water soluble resin, 1-3% of leveling agent and the balance of water. According to the coating, the nano-grade conductive silver wires prepared by using an etching method are blended into the water soluble or oil soluble resin, so that the conductivity of the coating is greatly improved; compared with the prior art, the coating is very low in preparation cost, simple in preparation method, small in amount of added additives, gentle and free of pollution in reaction condition, and applicable to scale production, and the raw materials are low in price and easily obtained.

Description

technical field [0001] The invention relates to a conductive coating, in particular to a water-soluble nano-silver conductive coating and an oil-soluble nano-silver conductive coating. Background technique [0002] Originating from the needs of flat panel display production, since Badeker reported the formation of cadmium oxide transparent conductive film by thermal evaporation of cadmium, the research and development of transparent conductive film has been widely valued. In the 1960s, indium tin oxide (ITO) became the main body of transparent conductive films, and then developed metal-based composite conductive films and aluminum-doped zinc oxide (AZO) films. Since the 1990s, with the development of the optoelectronics industry, multi-component Transparent conductive oxide (TCO) materials, conductive polymer films and other transparent conductive materials are applied. [0003] At present, the most widely used transparent conductive film is prepared on hard materials such ...

Problems solved by technology

[0004] In the past ten years, research on flexible transparent conductive films has been in the ascendant worldwide, and a variety of transparent conductive materials have been developed, such as conductive polymers, carbon nanotubes, graphene, metal grids, and metal nanowires. It is only in the research stage and cannot be produced in large quantities. The conductivity of carbon nanotubes is relatively poor and cannot be bent. The conductivity and stability of conductive polymers are not satisfactory. Therefore, the most promising industrialization is conductive metals. Some well-known foreign companies Different technologies have been used in trial production or mass production of flexible transparent conductive films, such as silver grid etching method, copper evaporation method, due to copper evaporation, silver grid etching process is complicated, production conditions are harsh, and equipment investment is too high
