Ti₃C₂T_XMXene Beaded SiC Nanowires for Efficient Microwave Absorption

Flexible SiCnw is anticipated to enable multifunctional uses of materials, such as wearable electronic components or coatings that absorb microwaves at high temperatures. By regulating the amount of raw materials, a beaded SiC nanowire (SiCnw) comprising SiC stems (150 nm) and SiO2 beads (600 nm) was successfully manufactured in this study. In addition, the Ti3C2TX MXene hybrid beaded SiCnw (M-SiCnw) film was produced using a straightforward suction filtration technique. The incorporation of Ti3C2TX MXene nanosheets and bead flaws created abundant interfaces and increased conductivity, hence boosting the microwave absorption efficiency. At a thickness of 1.58 mm and an effective absorption bandwidth of 3.36 GHz, a minimum reflection loss value of −41.7 dB was observed. The possible absorption process of the M-SiCnw film is elaborated upon. The results demonstrate that the M-SiCnw film has promising future applications in membrane technology and microwave absorption.
