The Separation Power of Highly Porous 3D Nanofiber Sponges.

Sponges formed by the self-assembly of nanofiber building blocks are versatile materials used in various fields such as filtration, thermal insulation, scaffolding or sound absorption. Their potential seems to be constantly expanding given the variety of possible fiber materials, from bio-based to fossil polymers to inorganic nanofibers. In general, nanofiber sponges - also called nanofiber aerogels - are flexible, have low density, and a large specific surface area thanks to their tunable open-porous nanofiber based architecture.
