Abstract
Terahertz (THz) absorption technology is promising in radar stealth, electromagnetic interference (EMI) shielding, and the upcoming 6G communication. However, the most popular metamaterial-based THz absorbers suffer from complex fabrication process and/or narrowband characteristics. Here, a broadband, lightweight, and hydrophobic THz absorber is realized based on Ti(3)C(2)T(x)MXene sponge foam (MSF) that is obtained by using a dip-coating method. Due to the macroscopic impedance matching to free space and various microscopic morphologies of metallic Ti(3)C(2)T(x)flakes inside porous architecture, the obtained MSF, with only 2 mm thickness, shows almost no THz reflection (minimum approximate to 0.00003%) and high THz absorption over 99.99% under the 100% qualified frequency bandwidth ranging from 0.3 to 1.65 THz. The new strategy of combining large-pore-size porous architecture with MXene-like 2D metallic flakes paves a way to achieving high performance THz absorber with minimal thickness, which is of significance in electromagnetic stealth, shielding, and beyond.
