Abstract

The invention provides a carbon nano material / metal nano material composite nano ink which comprises solvent, an additive, a carbon nano material and a metal nano material. The carbon nano material / metal nano material composite nano ink is characterized in that the solvent can comprise water, alcohol organic solvent (ethanol(alcohol), isopropanol, n-butanol and the like), ester organic solvent (ethyl acetate, butyl acetate, ethylene-propylene acetate and the like), benzene organic solvent (methylbenzene, dimethylbenzene and the like) and ketone organic solvent (cyclohexanone, acetone, methylethylketone, butanone and the like); the additive comprises surfactant, pH value stabilizer, defoaming agent, diluter, reinforcer and the like; the carbon nano material comprises a single-layer carbon nanotube, a double-layer carbon nanotube, a multi-layer carbon nanotube and graphene; the metal (copper, silver, gold, platinum, nickel and the like, also including an alloy nano material, an ITO metal composite nano material and the like) nano material further comprises a metal nanoparticle, a metal nanowire or a metal nanotube; the components of the nano ink must include one carbon nano component and one metal nano component, such as a single-layer carbon nanotube and copper nanowire composite ink, a double-layer carbon nanotube and silver nanowire composite ink, a single-layer carbon nanotube and silver nanoparticle composite ink or any other possible combination; the components can be regulated according to specific applications; and a composite nano conductive film can be formed on different bases through different electronic printing processes. The ink can be used in the printing of a flexible base material and can be conveniently prepared into a flexible conductive film.

Description

technical field [0001] The invention relates to the field of ink, and is a conductive ink prepared based on nanometer materials. Background technique [0002] To put it simply, a transparent electrode must be able to conduct electricity, and the second must be able to transmit light. The market prospect of transparent electrodes in the world is broad. Furthermore, transparent electrodes are not only widely used in touch screens. In the near future, they will also be used in flat panel displays, LCDs, organic LED (OLED) lighting, solar cells and other fields. Applications. [0003] The transparent electrode material widely used at present is ITO (Indium Tin Oxide). ITO has obvious advantages as a transparent electrode material, that is, high transparency and good conductivity, and it shows high performance in many applications. At present, the main preparation method of ITO transparent electrodes is the vacuum evaporation process, which has complicated process, expensive e...

Problems solved by technology

However, silver, like indium, is rare and expensive, and the cost of developing and producing products is high

Recently, researchers at home and abroad are making great efforts to improve the performance of carbon nanotubes (CNT) and research in the film coating industry, but no breakthrough has been made so far.
