‘Green’ foam that’s cheap and dirty
“The flexibility of the clay aerogel composites is amazing,” says engineering professor David Schiraldi, who adds that almost anyone can make the composites if they have pure clay in a form that resembles cat litter pellets, a blender, and a $50,000 freeze dryer.
