Cellulose Nanofibers modified with alkyl ketene dimer for oil absorbent aerogels

Nanofibrillated cellulose consists of interconnected cellulose nanofibers, isolated from wood or agricultural byproducts, which leads to a three dimensional, porous and flexible structure. In this sense, the present work aims to develop hydrophobic aerogels for oil absorbing. Different percentages o...
