Abstract

The invention provides a graphene electrothermal material and application thereof. The graphene electrothermal material is mainly composed of graphene, other carbon-based materials and a solvent, the weight ratio of graphene to the other carbon-based materials is 0.5-10:1, preferably 2-10: 1 and 5-10:1, and the other carbon-based materials include one or multiple selected from carbon fiber, graphite and carbon nanotubes, preferably carbon fibers. The graphene electrothermal material has the advantages of being energy-saving, light, high in flexibility, uneasy to oxidation, high in electric and thermal conductivity, wide in application range and capable of being used in large area, and can be used in the fields including clothes manufacture, nursing, aviation equipment, medical equipment, household heating equipment and automobile.

Description

technical field [0001] The invention relates to the field of electrothermal materials, in particular to a graphene electrothermal material and its application. Background technique [0002] With the continuous depletion of coal, oil, natural gas and other non-renewable resources and the increasingly serious environmental pollution, it is particularly urgent and important to research and develop renewable, green and clean energy and its supporting industrial products and daily necessities. Under the background that solar energy, nuclear power, hydropower and wind power replace non-renewable resources to generate heat and generate electricity, many industrial products and daily necessities are paying more and more attention to energy conservation and emission reduction. In addition, as people's demand for product portability and wearable performance increases, low-energy, light-weight and integrated products have shown huge market potential. [0003] As an emerging carbon mat...
