Abstract: With its advantages of rapid response, strong controllability and high stability, electricthermal anti/de-icing has become the most potential anti/de-icing technology for aircraft wings, which is currently only used in B787 wings, but the metal electric heating elements used in it have problems such as slow heating speed and low energy utilization, resulting in the power consumption of the system accounting for nearly a quarter of the generator power. Carbon nanomaterials are ideal electrothermal materials due to their excellent electrical and thermal conductivity. In this paper, the preparation method and electrothermal properties of carbon nanomaterial electric heating elements, as well as the design and anti/de-icing performance of their electric heating structures combined with composite materials, provide a reference for the development of a new generation of high-efficiency and energy-saving electric heating elements that are more suitable for composite materials, and provide a reference for the construction of a new type of electric thermal anti/de-icing system for aircraft wings.
