Abstract

The invention discloses a flexible composite transparent conductive film, which comprises a polyethylene glycol terephthalate substrate layer, a blending layer of nanocellulose and silver nanowires and a graphene oxide layer in sequential contact, and is characterized in that the nanocellulose has a three-dimensional network porous structure and is used as a support body material to bear the silver nanowires; the silver nanowires are spread on the surface of the nanocellulose and are uniformly dispersed, so that the agglomeration phenomenon of the silver nanowires is reduced, the film-formingproperty of the silver nanowires is good, and the surface is flat and uniform.

Description

technical field

[0001] The invention relates to the field of optoelectronic technology, in particular to a flexible composite transparent conductive film and a preparation method thereof. Background technique

[0002] In recent years, with the rapid development of flexible optoelectronic devices, flexible transparent conductive films have been widely used in touch screens, sensors, solar cells, transparent heaters and other fields. At present, indium tin oxide (ITO) has been widely used in the preparation of electrode materials for optoelectronic devices. As an oxide conductor, it has many advantages, such as high stability in the atmosphere and high light transmittance. However, with the development of flexible electronic devices, traditional ITO transparent conductive films have also exposed more and more shortcomings, such as brittleness, shortage of indium resources, and high cost. Therefore, it is imminent to find materials that can replace ITO. Among them, graphene, c...
