Abstract: The platanus catkin can cause respiratory and eye diseases in certain individuals. To mitigate its environmental pollution and utilize the fruit of the platanus orientalis, derived carbon was gotten through high-temperature carbonization, then impregnated with silica sol, and heated at high-temperature, silicon carbide nanowires/platanus catkin-derived carbon (SiCnw/PCD-C) composites were obtained. The microstructure of the platanus orientalis fruit and the effects of the addition amount of silica sol and heating temperature on the phase composition, microstructure, and microwave absorption properties of the sample were investigated. The results indicate that the obtained SiCnw/PCD-C composite exhibits the best microwave absorption performance, with an effective absorption bandwidth of 4.48 GHz, corresponding minimum reflection loss of −31.8 dB, and a matching thickness of only 1.5 mm when the mass ratio of derived carbon to silica sol is 3:2 and the reaction temperature is 1400 °C under an Ar atmosphere. The synergistic effect of silicon carbide nanowires and derived carbon enables the SiCnw/PCD-C composite to exhibit excellent microwave absorption performance at a relatively thin thickness. This paves a new path to benefit the utilization of platanus catkin. [ABSTRACT FROM AUTHOR]
