Fig. 2From: Characterization of dual nano-size effects of ACC-cellulose nanofibrils on crystallization behavior of hydrophilic poly(vinyl alcohol)Schematic diagram of cross-sectional image of CNFs. Left image is used for calculation of whole volume for a single CNF, and right image represents calculation of interior volume of a single CNF. Difference between the two volumes indicates surface skin volume of a single CNFBack to article page
