Influence of fibrillation method on the character of nanofibrillated cellulose (NFC)

摘要

Increasing research efforts have been directed towards the production and analysis of the properties of nanofibrillated cellulose (NFC), aiming for industrial exploitation in various material applications. Different fibrillation methods, mechanical and chemical, yield fibrils with varying size distributions and length/diameter-ratios. Indirect methods, such as turbidity, can be used to estimate fibril size. However, direct and accurate assessment of the NFC fibril dimensions may bring a new understanding of the fibrillation mechanisms. High-resolution microscopy renders this possible.
