Problems solved by technology
[0002] In recent years, with the continuous development of electronic science and technology, various electronic products have become more and more popular, and the market demand has continued to expand. As a key part of many electronic devices, such as liquid crystal displays and touch screens, transparent conductive films have received more and more attention. Transparent conductive film is a film material with high light transmittance and excellent conductivity in the visible light range. Transparent conductive film is widely used in liquid crystal displays, touch screens, thin-film solar cells, light-emitting devices and electromagnetic shielding devices. Although At present, transparent conductive films based on metal oxides are relatively mature in the market, but there are still many shortcomings. Research on transparent conductive films at home and abroad has gradually become a hot spot. People expect to develop some new production processes, or develop some new types of transparent conductive films. Conductive thin film materials to overcome these disadvantages

Abstract
The invention discloses an epoxygrapheneoxide film and a preparation method thereof. The epoxygrapheneoxide film consists of the following raw materials in parts by weight: 30-40 parts of epoxyemulsion, 100-110 parts of grapheneoxide, 6-10 parts of diethylenetriamine, 2-4 parts of aluminium dihydrogen phosphate, 0.8-1 part of zincstearate. According to the epoxy graphene oxide film, diethylenetriamine is adopted to process the aluminium dihydrogen phosphate so as to be mixed with the dispersion liquid of graphene oxide, amine is used for accelerating environment to open a loop so as toimprove the surface activity of aluminium dihydrogen phosphate and graphene oxide, inter-dimethylformamide dispersion compatibility is further improved, and the mechanical stability and the evenness of a finished product film can be improved.
