This chapter begins with a brief introduction and definition of nanocellulose substrates. Next, it summarizes several key advances in the chemical modification routes for the functionalization of nanocelluloses. Taking advantage of the large number of hydroxyl groups at the surface of nanocellulose substrates, different chemical modifications have been attempted, including esterification, etherification, oxidation, silylation, amidation, and polymer grafting. Noncovalent surface modification, including the use of adsorbing surfactants and coupling agents, is also studied. The main challenge for the chemical functionalization of the different nanocellulose substrates is to conduct it in such a way that it only changes their surface while preserving their original morphology, avoiding any polymorphic conversion, and maintaining the integrity of their native crystalline structure.
