Summary

The three most abundant renewable polysaccharides in nature share rather similar building blocks, but they exhibit quite different properties because the existing differences in molecular structure lead to different arrangements and supramolecular structures. In particular, surface modification is performed to improve interfacial compatibility and dispersion if the intended use of the nanoparticles is polymer reinforcement, or to achieve specific interactions with other material components if functional properties are required. Many studies have reported on the WAXD of different cellulose sources and cellulose nanofibers extracted by different methods. The chapter presents various examples on the use of spectroscopies applied to renewable nanoparticles and derived nanocomposites in order to give a glimpse into the different approaches to characterize materials and identify bulk and surface modifications.
