MXene guides microwaves through 3D polymeric structures
With the advances in space technology, weight reduction of components has been a paramount, yet challenging task. Additive manufacturing with high-performance polymers can realize lightweight and complex geometries that can also be manufactured on board. Yet polymers are electromagnetically inefficient for applications requiring electrical conductivity, such as guiding microwave signals. This work presents high-efficiency and lightweight additively-manufactured microwave components enabled by MXene coating. The waveguiding functionality was observed from 8 to 33 GHz, covering low earth orbit (LEO) frequencies, with a power-handling capability of up to 10 dB and a transmission coefficient of 93 %. After a single dip-coating cycle, the polymer waveguide performed only 2 % below an eight times heavier metallic equivalent. Frequency/polarization filtering was enabled by implementing special geometries, and a range of microwave functionalities, including resonance, was demonstrated. The MXene-coated components can replace 3D-printed and bulk metals, greatly decreasing weight and cost in space, and also in various terrestrial applications.
