Multifunctional SiC@SiO₂ Nanofiber Aerogel with Ultrabroadband Electromagnetic Wave Absorption.

ABSTRACT: Traditional ceramic materials are generally brittle and not flexible with high production costs, which seriously hinders their practical applications. Multifunctional nanofiber ceramic aerogels are highly desirable for applications in extreme environments, however, the integration of multiple functions in their preparation is extremely challenging. To tackle these challenges, we fabricated a multifunctional SiC@SiO₂ nanofiber aerogel (SiC@SiO₂ NFA) with a three-dimensional (3D) porous cross-linked structure through a simple chemical vapor deposition method and subsequent heat-treatment process. The as-prepared SiC@SiO₂ NFA exhibits an ultralow density (~ 11 mg cm^- 3), ultra-elastic, fatigue-resistant and refractory performance, high temperature t
