Microwave attenuation, lightweight, flexibility and thermal insulation performance of SiOC amorphous nanofibers

Caption

The incorporation of Co and Ti significantly facilitated the nanostructuring of the fibers and enhanced the dielectric loss of the fiber films. With only a 5 wt% fiber filling content, CTS-800 demonstrates excellent microwave absorption properties, including strong absorption (minimum reflection loss, RLmin: -66.0 dB), a thin thickness (2.5 mm), and an impressive effective absorption bandwidth (EAB: 8.64 GHz). Additionally, the nanostructuring of the fibers and the three-dimensional network structure imparted by electrospinning facilitated the conduction and dissipation of external stress and heat. Herein, CTS-800 is a multifunctional composite material that integrates excellent microwave absorption performance, flexibility, compressive resilience, customizable properties, and thermal insulation. The successful preparation of such multi-functional nanofiber mats makes it promising perspectives for the application of thermal and microwave protection.
