The work aims to analyze the research status of liquid crystal graphene-based functional materials and the prospects of their application in electronic devices. The current functional graphene materials were reviewed in terms of the preparation, characterization and self-assembly property of thermally-induced and lyotropic liquid crystal graphenes; and the effects of graphene self-assembly properties on the electrical properties of electronic devices were systematically analyzed and discussed. The liquid crystal graphene structure had been found to strongly affect the electrical properties. The self-assembly technology achieved the highly ordered graphenes and improved their electrical properties. The self-organization liquid crystal graphene-based functional materials can realize the preparation of high-performance electronic devices, thereby enabling their broad application in electronic devices.
