Description

technical field [0001] The invention relates to the technical field of carbon materials, in particular to a graphene heating film and a preparation method thereof. Background technique [0002] Electric heating technology has significant advantages such as clean energy, high heat conversion efficiency, and convenient pavement design, and has been widely used in modern architecture, heating engineering, decoration and other fields. In view of the shortcomings of low efficiency of traditional electric heating technology, the development of high-performance carbon-based heating materials with low resistance, high thermal conductivity, and high heat resistance stability is becoming an inevitable trend of future development. [0003] Graphene is a new type of carbon thin film material that is arranged in a hexagonal network structure by a single layer of carbon atoms. The electron and hole carrier mobility in single-layer graphene is expected to reach a maximum of 100 times that...
