Ultralight aerogels combine broadband microwave absorption with thermal insulation
Researchers developed lightweight carbon aerogels with CoNi components that deliver wide electromagnetic-wave attenuation at low density and low filler loading. The aerogels also exhibit thermal insulation, limiting heat transfer and maintaining a stable surface temperature even at high temperatures.
