Polymer modification oxidation-reduction properties

Apart from the production process of NFC by homogenization, their final application is a critical issue. Because of the hydrophilic nature of cellulose nanofibers, their incorporation and dispersion with common polymers, which are hydrophobic, are very critical issues [38]. Low interfacial adhesion between these two parts in composite leads to reduction in the mechanical and other properties of the final product. Thus, a wide variety of modifications like carboxymethylation [65], 2,2,6,6-tetramethylpiperdine-1-oxyl (TEMPO) oxidation [66, 67], acetylation [68, 69], and silylation [70, 71] have been designed to overcome this problem. The modification strategies of cellulose nanosize materials are discussed in Section 11.6.
