Silicon carbide nanowire (SiC NW), as a typical wide band gap semiconductor was used as light‐emitting materials and devices in high‐temperature and harsh environments due to its excellent properties. In this paper, flexible ultra‐long SiC NWs membrane was successfully synthesized by electrospinning and subsequently high‐temperature sintering using phenolic resin and silica sol as precursors. Results of system characterization reveal that SiC NWs possess a smooth and uniform surface with diameter distribution mainly between 50‐300 nm and a length of more than tens of micrometers, forming a network structure. The growth mechanism of synthesized nanowires was mainly carbothermal reduction in situ and was accompanied by vapor‐solid (V‐S) reaction. The present work provides a simple and cost‐effective way for controllable fabrication of SiC NWs membrane. The photoluminescence spectrum of SiC NWs membrane emerged a clear blue shift, indicating a potential application in optoelectronic devices and discussed the potential applications of SiC NWs membrane in other fields.

“…The minimum reflection loss was measured as −40.38 dB at 14.1 GHz for the SiC/ZrC/SiZrOC hybrid nanofibers and they were suggested as promising high temperature microwave-absorbing materials [72]. Using a combined process of electrospinning and calcination, Huo et al [73] produced silicon carbide/carbon (SiC/C) hybrid nanofibers, which possessed a high aspect ratio and a scaly surface.…”

Ceramic materials are well known for their hardness, inertness, superior mechanical and thermal properties, resistance against chemical erosion and corrosion. Ceramic nanofibers were first manufactured through a combination of electrospinning with sol–gel method in 2002. The electrospun ceramic nanofibers display unprecedented properties such as high surface area, length, thermo-mechanical properties, and hierarchically porous structure which make them candidates for a wide range of applications such as tissue engineering, sensors, water remediation, energy storage, electromagnetic shielding, thermal insulation materials, etc. This chapter focuses on the most recent advances in the applications of ceramic nanofibers.

“…The minimum reflection loss (RL min ) of −38.1 dB could be displayed in hybrids (20 wt % of the filling content), but the corresponding matching thickness climbed to 5 mm. Huo et al managed to fabricate the SiC/C hybrid nanofibers membrane through electrospinning and pyrolysis procedures, and the as-obtained products with the mixing ratio of 30 wt % exhibited the RL min of −36 dB at 3 mm and EAB of 4.1 GHz with a thickness of 1.5 mm. Novel ZnO/C nanofibers were designed by Gu et al using ZIF-8/PAN nanofibers prepared by the electrospinning technique as precursor via the carbonization process and demonstrated EMW absorbency with the RL min of −22.89 dB at 1.5 mm and EAB of 4.4 GHz corresponding to 1.8 mm when the filler loading was 20 wt %.…”

An enormous challenge exists in the achievement of one-dimensional (1D) dielectric carbon composite high-performance microwave absorbents at a low filling ratio. Porous/core− shell dual microstructures have been considered as the potential candidate for designing remarkable microwave absorbers with strong absorption and wide band. Herein, novel multiplestructured tubular carbon nanofibers@TiO 2 (TCNFs@TiO 2 ) hybrids were constructed via the sequential steps of hydrolysis and pyrolysis. The dielectric properties of the as-prepared composites can be tuned by adjusting the relative content of the TiO 2 shell and carbonaceous temperature to enhance the impedance matching behavior. Notably, the minimum reflection loss (RL min ) value reaches up to −61.2 dB with an effective absorption bandwidth (EAB) of 3.2 GHz at 3 mm, and the EAB can cover 5.3 GHz with a thickness of merely 2 mm when 1.3 mL of tetrabutyl titanate (TBT) and 700 °C pyrolysis temperature are optimized, respectively. Delightedly, the mixing ratio is only 10 wt %, outperforming that of the most-related composites. The heterogeneous interfaces in TCNFs−TiO 2 are beneficial for the interfacial polarization relaxation. Besides, the hybrids are enriched with numerous pores to favor the lightweight absorbers. The desirable design in the microstructure can provide a promising route in wide-band and lightweight microwave absorbents.
