An international team of researchers (Switzerland, Singapore) used nanofibers of cellulose as the basis for making an aerogel which is a light, highly porous material. Cellulose fibres obtained from wood enable a wide range of chemical modifications. The composite of cellulose nanofibers and silver nanowires created ultra-light fine structures which provide excellent shielding against electromagnetic radiation. The material has a density of 1.7 milligrams per cubic centimeter, achieves more than 40 dB shielding in the frequency range of high-resolution radar radiation (8 to 12 GHz) – in other words: virtually all radiation in this frequency range is intercepted by the material…read more.
