Abstract
Wave-transparent materials are essential to ensure the high-fidelity transmission of electromagnetic waves and to safeguard antenna systems in critical fields such as aerospace, transportation, and communication. However, surface icing of wave-transparent materials or antennas will severely impact their transmission and aerodynamic performance. In this study, a patterned electrothermal composite film (PEF) was prepared and optimized by relevant theories of electromagnetic leakage and frequency selective surface. The PEF demonstrated excellent rapid heating and stability, requiring only 0.4 W/cm2 power density to completely anti-ice in dynamic icing experiments. Additionally, the PEF boasted high transmittance, exceeding 80 % across an ultra-broadband range of 2–18 GHz. Furthermore, the PEF was lightweight and could be prepared in a large area. The results suggest that the PEF has the potential for valuable applications in radar radomes, wave-transmitting walls, and protective walls, particularly in cold areas.
