A "Smart Sponge" Soaks Up Pollutants
Snapshot: This "smart sponge" is one of a number of applications under development for the tiny wood fibers known as cellulose nanofibrils (CNF). The fibers possess a number of unique properties including renewability, high surface areas, high aspect ratios, and excellent mechanical properties. CNF-based superabsorbent aerogels exhibit ultralow density, high porosity, high specific surface area, high flexibility, and low thermal conductivity.
Cellulose nanofibril smart sponge absorbs oil which is floating on the top of water. Bryce Richter, University of Wisconsin
