Problems solved by technology

However, in the current existing technology, although there are cases of preparing transparent conductive films by combining one-dimensional and two-dimensional nanomaterials, and there are also cases of preparing transparent conductive films by electroless gold plating on nanomaterials to improve their conductivity, but the thin film Conductivity and light transmission are still limited, so there is an urgent need for a thin film material with excellent conductivity and light transmission to meet the application requirements.

Description

technical field [0001] The invention relates to the field of transparent conductive films, in particular to a method for preparing a carbon nanotube composite transparent conductive film. Background technique [0002] Indium tin oxide (ITO) is currently the most widely used transparent electrode material, and is used in display screens, touch screens, transparent electrodes and other fields. However, with the continuous development of electronic devices in the direction of light weight, small size and flexibility, the traditional ITO has poor flexibility and is too expensive to meet people's needs. Therefore, the development of transparent conductive film materials with excellent photoelectric performance and bending resistance has become the focus of research and development personnel. Among these materials, one-dimensional nanomaterials such as carbon nanotubes, metal nanowires, and two-dimensional nanomaterials graphene and MXene are the main ones. This type of material ...
