Nanocellulose is a fibrous material derived from wood that is applied to composite materials and is attracting attention as an advanced material. Cellulose nanofibers (CNFs) are mechanically disintegrated materials with a diameter of 4~20nm, while cellulose nanocrystals (CNCs) are chemically disintegrated, needle-like materials with a diameter of 4~10nm. In order to actually utilize nanocellulose, it is important to understand the fiber diameter and dispersion state.
3 types of nanocellulose (one type of CNF and two types of CNC) were analyzed using the Partica CENTRIFUGE centrifugal nanoparticle analyzer. The results were correlated with fiber diameter (height) measurements by atomic force microscopy (AFM).
