text: The most important properties are: 1) Aspect ratio, i.e., the diameter and length of the fibrils; 2) Range of polydispersity (the preparations are usually mixtures of fibrils with different size distribution); 3) Surface chemistry, specifically how the surface has been modified by adding chemical functionalities, such as charge, hydrophobic groups, etc.; and 4) Impurities and other polymers present (nanocellulose consists seldom of only cellulose, and other compounds present may have a major impact on the properties of the preparation).
