Ultralight biomass-derived carbon fibre aerogels for electromagnetic and acoustic noise mitigation

Abstract

The silkworm derived carbon fibre aerogel (SA) could be a promising building material to address the ever-growing noise (EM and sound) issues and improve the energy efficiency of the architectures.

Direct synthesis of ultralight, elastic, high-temperature insulation N-doped TiO2 ceramic nanofibrous sponges via conjugate electrospinning

“…By adding inorganic fillers, such as silicates and clay, organic inorganic hybrid aerogels can be prepared, and the flame retardation can be increased to 400 °C, 47 or even about 600 °C. 48,49 Silicon aerogels 50,51 and carbon aerogels 52,53 were used at higher temperatures; however, structural contraction and combustion still occurred when exposed to fire above 600 °C. The prepared N-TiO 2 CNSs have not only thermal resistance and low density similar to common ceramic aerogels, but also superelasticity similar to polymer elastomers.…”

Robust graphene-drum bridged carbon aerogels for broadband acoustic and electromagnetic attenuation

“…5h provides a comprehensive assessment of Gd-CAs by comparing them with newly reported graphene/carbon-based porous materials in terms of wave pollution attenuation, functionality, and practical applications. 32,35,39,63,64 The evaluation considers ve key metrics: robustness, EMW attenuation, acoustic wave absorption, multifunction, and strain-sensing performance. The benchmarks for these comparisons are specied in Table S3.…”

Biomimetic Sea Urchin-like Nano-ferrite Structures for Microwave Absorption

“…Electronic equipment and wireless communication have played a significant role in the work and life of people. , However, electromagnetic (EM) interference in electronic devices can lead to malfunction and degradation of other electronic equipment, while endangering people’s health. − In this case, there is always a demand for developing EM-absorbing materials to eliminate harmful EM pollution. Due to the long electromagnetic wave (EMW) wavelength, the development of efficient microwave absorbers for the low-frequency band remains a great challenge.…”
