Abstract

The invention belongs to the technical field of preparation of conducting materials, and specifically discloses preparation of a transparent conducting film based on nano-silver wires and caboxylated carbon nano-materials. The nano-silver wires can be well dispersed in solvents such as water and alcohols, carbon nano-materials are insoluble and difficult to disperse in water or an organic solvent, after being carboxylated, the carbon nano-materials can be well dispersed in the solvents and are used to prepare a mixed solution together with the nano-silver wires, and thus addition of auxiliaries such as dispersing agents, which makes post-treatment complex, can be effectively avoided. Surfaces of the nano-silver wires have electrophilic characteristics, and thus can be coordinated with atoms rich in electrons through coordination. Carboxyl groups in the prepared carbon nano-materials can be combined with the nano-silver wires, thereby enabling the nano-materials to better contact with the nano-silver wires and eliminating contact resistance to the greatest extent. Influences of the nano-silver wires and the carbon nano-mateirals in the aspect of light transmission are different, and mutual complementation can be realized, thereby enabling light transmission and electrical conductivity to be improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of conductive materials, in particular to a preparation technology of a flexible transparent conductive film, in particular to the preparation of a transparent conductive film based on nano-silver wires and carboxylated carbon nano-materials. Background technique [0002] Transparent conductive film means that the transmittance of visible light in the wavelength range between 380 and 780nm is greater than 80%, and the resistivity is lower than 10 -3 Ω·cm films. At present, the widely used transparent conductive film is mainly prepared on hard substrate materials such as ceramics and glass with ITO as the conductive material. The application of transparent conductive films is limited. In addition, although ITO has been successfully used as a transparent conductive film in optoelectronic devices for more than sixty years, it is completely unsuitable as a material for the preparation of flexibl...
