Recent Advances on Cellulose Nanocrystals and Their Derivatives [PDF]

open access: yesPolymers, 2021
Nanocellulose, typically cellulose nanocrystals (CNCs), has excellent properties and is widely used. In particular, CNC has a small dimension, high chemical reactivity, and high sustainability, which makes it an excellent candidate as a starting material to be converted into nanocellulose derivatives.
