Research Progress of Graphene Composites in the Field of Electrothermal Anti-Icing / Deicing

Aircraft anti-icing / deicing system is an important device to improve aircraft safety performance and reduce flight accidents caused by icing. Electrothermal anti-icing / deicing protection system has the advantages of high efficiency, uniform heating, flexible and convenient deicing mode, and is one of the important anti-icing / deicing methods at present. However, traditional electrothermal materials generally have the problem of high energy consumption, so the search for effective and energy-saving electrothermal materials has become the focus of current research. Graphene has a very broad application prospect in the field of electrothermal anti-icing / deicing because of its low resistivity and high thermal conductivity. In this paper, the aircraft electrothermal anti-icing / deicing device, its working principle and the research progress of electrothermal materials are introduced. Afterwards, the advantages and preparation methods of graphene electrothermal materials are briefly described, with emphasis on the influence factors and improvement methods of its deicing efficiency. Finally, the research achievements of gra phene electrothermal deicing materials in recent years are summarized and the future development is prospected.
