|Abstract:||A cost effective and scalable recipe for fabricating biodegradable cellulose aerogels from paper waste has been realized. The green aerogel is macroporous and has extremely low density and thermal conductivity: 0.04gcm-3 and 0.029-0.032Wm-1K-1, respectively. It is highly absorbent, absorbing 18-20 times its weight in liquid. Up to 99.8% of the liquid is recovered simply by squeezing the aerogel. The fabrication can be optimized for absorbing polar (water) or non-polar liquids (oil). Coating the aerogel with methyltrimethoxysilane improves its hydrophobicity without affecting its absorbency. Mechanically, the aerogel is flexible yet strong making a wide range of applications possible. © 2014 Elsevier B.V.|
