Abstract
The present disclosure relates to a process for preparing coated cellulose nanocrystals (CNCs) and relates as well to coated cellulose nanocrystals (CNCs) obtainable by the process described herein. These new CNC hybrid nanomaterials are expected to be useful, for example, for the conjugation and electrostatic complexation with various functional moieties such as free metal ions, carboxylic acids, and epoxy and aldehyde derivatives. The disclosure further relates to a method to fabricate N-doped carbon nanomaterial from the coated CNCs.
