Nanofoams are a class of nanostructured, porous materials, foams, containing a significant population of pores with diameters less than 100 nm. Aerogels are one example of nanofoam.[1]

Metal nanofoams[edit]

In 2006, Dr. Bryce Tappan, Dr. Steven F. Son and coworkers at Los Alamos National Laboratory discovered a technique for producing metal nanofoams by igniting pellets of energetic metal bis(tetrazolato)amine complexes. Nanofoams of iron, cobalt, nickel, copper, silver, and palladium have been prepared through this technique. These materials exhibit densities as low as 11 mg/cm3, and surface areas as high as 258 m2/g. These foams are effective catalysts and are being investigated for other applications.[2]

One of the reasons this new nanofoam is so successful is due to the unique properties of graphene oxide. GO is a modification of graphene, which can be produced much more cheaply, but still maintains some of the most important attributes of the ...

The team discovered that the foam with the smallest pores -- the 10 nm pore-size nanofoam -- absorbed impacts the best. Larger foams suffered so-called "damage localization" when exposed to trauma. The energy absorbed was poorly distributed, leading to ...
