Microscopic Analysis of Cellulose Nanofibril ( CNF )‐ and Cellulose Nanocrystal ( CNC )‐Based Nanocomposites

Evaluating the successful incorporation of nanocellulose into nanocomposites is a challenging endeavor, especially their dispersibility and distribution in the nanocomposites. Microscopic techniques have been applied in nanocomposite formulation to comprehend these issues. In this chapter applications and limitations of optical microscopy, scanning electron microscopy, and atomic force microscopy in nanocomposite development are examined with different types of nanocomposites containing either cellulose nanocrystals or cellulose nanofibrils. Lastly, strategies in sample preparation to enhance the resolution in imaging are discussed.
